Myosin and Kinesin motor domain; Myosin and Kinesin motor domain. These ATPases belong to the P-loop NTPase family and provide the driving force in myosin and kinesin mediated processes. Some of the names do not match with what is given in the sequence list. This is because they are based on the current nomenclature by Kollmar/Sebe-Pedros.

1-226 7.74e-148

class II myosin heavy chain 3, motor domain; Myosin motor domain of fetal skeletal muscle myosin heavy chain 3 (MYHC-EMB, MYHSE1, HEMHC, SMHCE) in tetrapods including mammals, lizards, and frogs. This gene is a member of the MYH family and encodes a protein with an IQ domain and a myosin head-like domain. Mutations in this gene have been associated with two congenital contracture (arthrogryposis) syndromes, Freeman-Sheldon syndrome and Sheldon-Hall syndrome. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

1-226 3.22e-140

class II myosin heavy chain 6, motor domain; Myosin motor domain of alpha (or fast) cardiac muscle myosin heavy chain 6. Cardiac muscle myosin is a hexamer consisting of two heavy chain subunits, two light chain subunits, and two regulatory subunits. This gene encodes the alpha heavy chain subunit of cardiac myosin. Mutations in this gene cause familial hypertrophic cardiomyopathy and atrial septal defect. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 7, motor domain; Myosin motor domain of beta (or slow) type I cardiac muscle myosin heavy chain 7 (also called CMH1, MPD1, and CMD1S). Muscle myosin is a hexameric protein containing 2 heavy chain subunits, 2 alkali light chain subunits, and 2 regulatory light chain subunits. It is expressed predominantly in normal human ventrical and in skeletal muscle tissues rich in slow-twitch type I muscle fibers. Changes in the relative abundance of this protein and the alpha (or fast) heavy subunit of cardiac myosin correlate with the contractile velocity of cardiac muscle. Its expression is also altered during thyroid hormone depletion and hemodynamic overloading. Mutations in this gene are associated with familial hypertrophic cardiomyopathy, myosin storage myopathy, dilated cardiomyopathy, and Laing early-onset distal myopathy. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together.

Mutations in this gene results in inclusion body myopathy-3 and familial congenital myopathy. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 16, motor domain; Myosin motor domain of myosin heavy chain 16 pseudogene (also called MHC20, MYH16, and myh5), encoding a sarcomeric myosin heavy chain expressed in nonhuman primate masticatory muscles, is inactivated in humans. This cd contains Myh16 in mammals. MYH16 has intermediate fibres between that of slow type 1 and fast 2B fibres, but exert more force than any other fibre type examined. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together.

Myosin motor domain superfamily; Myosin motor domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 2, motor domain; Myosin motor domain of type IIa skeletal muscle myosin heavy chain 2 (also called MYH2A, MYHSA2, MyHC-IIa, MYHas8, MyHC-2A) in insects and mollusks. This gene encodes a member of the class II or conventional myosin heavy chains, and functions in skeletal muscle contraction. Mutations in this gene results in inclusion body myopathy-3 and familial congenital myopathy. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

1-226 2.05e-68

class V myosin, motor domain; Myo5, also called heavy chain 12, myoxin, are dimeric myosins that transport a variety of intracellular cargo processively along actin filaments, such as melanosomes, synaptic vesicles, vacuoles, and mRNA. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. It also contains a IQ domain and a globular DIL domain. Myosin V is a class of actin-based motor proteins involved in cytoplasmic vesicle transport and anchorage, spindle-pole alignment and mRNA translocation. The protein encoded by this gene is abundant in melanocytes and nerve cells. Mutations in this gene cause Griscelli syndrome type-1 (GS1), Griscelli syndrome type-3 (GS3) and neuroectodermal melanolysosomal disease, or Elejalde disease. Multiple alternatively spliced transcript variants encoding different isoforms have been reported, but the full-length nature of some variants has not been determined. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. Note that the Dictyostelium myoVs are not contained in this child group. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 10, motor domain; Myosin motor domain of non-muscle myosin heavy chain 10 (also called NMMHCB). Mutations in this gene have been associated with May-Hegglin anomaly and developmental defects in brain and heart. Multiple transcript variants encoding different isoforms have been found for this gene. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail.

Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class I myosin, motor domain; Myosin I generates movement at the leading edge in cell motility, and class I myosins have been implicated in phagocytosis and vesicle transport. Myosin I, an unconventional myosin, does not form dimers. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. There are 5 myosin subclasses with subclasses c/h, d/g, and a/b have an IQ domain and a TH1 domain.

class II myosin heavy chain 11, motor domain; Myosin motor domain of smooth muscle myosin heavy chain 11 (also called SMMHC, SMHC). The gene product is a subunit of a hexameric protein that consists of two heavy chain subunits and two pairs of non-identical light chain subunits. It functions as a major contractile protein, converting chemical energy into mechanical energy through the hydrolysis of ATP. The gene encoding a human ortholog of rat NUDE1 is transcribed from the reverse strand of this gene, and its 3' end overlaps with that of the latter. Inversion of the MYH11 locus is one of the most frequent chromosomal aberrations found in acute myeloid leukemia. Alternative splicing generates isoforms that are differentially expressed, with ratios changing during muscle cell maturation. Mutations in MYH11 have been described in individuals with thoracic aortic aneurysms leading to acute aortic dissections with patent ductus arteriosus. MYH11 mutations are also thought to contribute to human colorectal cancer and are also associated with Peutz-Jeghers syndrome. The mutations found in human intestinal neoplasia result in unregulated proteins with constitutive motor activity, similar to the mutant myh11 zebrafish. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 9, motor domain; Myosin motor domain of non-muscle myosin heavy chain 9 (also called NMMHCA, NMHC-II-A, MHA, FTNS, EPSTS, and DFNA17). Myosin is a hexameric protein composed of a pair of myosin heavy chains (MYH) and two pairs of nonidentical light chains. The encoded protein is a myosin IIA heavy chain that contains an IQ domain and a myosin head-like domain which is involved in several important functions, including cytokinesis, cell motility and maintenance of cell shape. Defects in this gene have been associated with non-syndromic sensorineural deafness autosomal dominant type 17, Epstein syndrome, Alport syndrome with macrothrombocytopenia, Sebastian syndrome, Fechtner syndrome and macrothrombocytopenia with progressive sensorineural deafness. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells.

1-209 4.72e-55

class VII myosin, motor domain; These monomeric myosins have been associated with functions in sensory systems such as vision and hearing. Mammalian myosin VII has a tail with 2 MyTH4 domains, 2 FERM domains, and a SH3 domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 14 motor domain; Myosin motor domain of non-muscle myosin heavy chain 14 (also called FLJ13881, KIAA2034, MHC16, MYH17). Its members include mammals, chickens, and turtles. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together.

Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. Some of the data used for this classification were produced by the CyMoBase team at the Max-Planck-Institute for Biophysical Chemistry. The sequence names are composed of the species abbreviation followed by the protein abbreviation and optional protein classifier and variant designations.

1-209 2.70e-52

class XXII myosin, motor domain; These myosins possess an extended neck with multiple IQ motifs such as found in class V, VIII, XI, and XIII myosins. These myosins are defined by two tandem MyTH4 and FERM domains. The apicomplexan, but not diatom myosins contain 4-6 WD40 repeats near the end of the C-terminal tail which suggests a possible function of these myosins in signal transduction and transcriptional regulation. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force.

Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle.

class XXIX myosin, motor domain; Class XXIX myosins are comprised of Stramenopiles and have very long tail domains consisting of three IQ motifs, short coiled-coil regions, up to 18 CBS domains, a PB1 domain, and a carboxy-terminal transmembrane domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class IV myosin, motor domain; These myosins all possess a WW domain either N-terminal or C-terminal to their motor domain and a tail with a MyTH4 domain followed by a SH3 domain in some instances. The monomeric Acanthamoebas were the first identified members of this group and have been joined by Stramenopiles. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments.

Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class VI myosin, motor domain; Myosin VI is a monomeric myosin, which moves towards the minus-end of actin filaments, in contrast to most other myosins which moves towards the plus-end of actin filaments. It is thought that myosin VI, unlike plus-end directed myosins, does not use a pure lever arm mechanism, but instead steps with a mechanism analogous to the kinesin neck-linker uncoupling model. It has been implicated in a myriad of functions including: the transport of cytoplasmic organelles, maintenance of normal Golgi morphology, endocytosis, secretion, cell migration, border cell migration during development, and in cancer metastasis playing roles in deafness and retinal development among others. While how this is accomplished is largely unknown there are several interacting proteins that have been identified such as disabled homolog 2 (DAB2), GIPC1, synapse-associated protein 97 (SAP97; also known as DLG1) and optineurin, which have been found to target myosin VI to different cellular compartments. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the minus end along actin filaments.

class XXXI myosin, motor domain; Class XXXI myosins have a very long neck region consisting of 17 IQ motifs and 2 tandem ANK repeats that are separated by a PH domain. The myosin classes XXX to XXXIV contain members from Phytophthora species and Hyaloperonospora parasitica.

class III myosin, motor domain; Myosin III has been shown to play a role in the vision process in insects and in hearing in mammals. Myosin III, an unconventional myosin, does not form dimers. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. They are characterized by an N-terminal protein kinase domain and several IQ domains. Some members also contain WW, SH2, PH, and Y-phosphatase domains. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force.

class X myosin, motor domain; Myosin X is an unconventional myosin motor that functions as a monomer. In mammalian cells, the motor is found to localize to filopodia. Myosin X walks towards the barbed ends of filaments and is thought to walk on bundles of actin, rather than single filaments, a unique behavior. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. C-terminal to the head domain are a variable number of IQ domains, 2 PH domains, a MyTH4 domain, and a FERM domain. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments.

class XLVII myosin, motor domain; The class XLVII myosins are comprised of Stramenopiles. Not much is known about this myosin class. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class XV mammal-like myosin, motor domain; The class XV myosins are monomeric. In vertebrates, myosin XV appears to be expressed in sensory tissue and play a role in hearing. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. C-terminal to the head domain are 2 MyTH4 domain, a FERM domain, and a SH3 domain. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class XIV myosin, motor domain; These myosins localize to plasma membranes of the intracellular parasites and may be involved in the cell invasion process. Their known functions include: transporting phagosomes to the nucleus and perturbing the developmentally regulated elimination of the macronucleus during conjugation. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. C-terminal to their motor domain these myosins have a MyTH4-FERM protein domain combination. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class XXXVI myosin, motor domain; This class of molluscan myosins contains a motor domain followed by a GlcAT-I (Beta1,3-glucuronyltransferase I) domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments.

class XIII myosin, motor domain; These myosins have an N-terminal motor domain, a light-chain binding domain, and a C-terminal GPA/Q-rich domain. There is little known about the function of this myosin class. Two of the earliest members identified in this class are green alga Acetabularia cliftonii, Aclmyo1 and Aclmyo2. They are striking with their short tail of Aclmyo1 of 18 residues and the maximum of 7 IQ motifs in Aclmyo2. It is thought that these myosins are involved in organelle transport and tip growth. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments.

class XIX myosin, motor domain; Monomeric myosin-XIX (Myo19) functions as an actin-based motor for mitochondrial movement in vertebrate cells. It contains a variable number of IQ domains. Human myo19 contains a motor domain, three IQ motifs, and a short tail. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle.

class XVII myosin, motor domain; This fungal myosin which is also known as chitin synthase uses its motor domain to tether its vesicular cargo to peripheral actin. It works in opposition to dynein, contributing to the retention of Mcs1 vesicles at the site of cell growth and increasing vesicle fusion necessary for polarized growth. Class 17 myosins consist of a N-terminal myosin motor domain with Cyt-b5, chitin synthase 2, and a DEK_C domains at it C-terminus. The chitin synthase region contains several transmembrane domains by which myosin 17 is thought to bind secretory vesicles. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class XXVIII myosin, motor domain; These myosins are found in fish, chicken, and mollusks. The tail regions of these class-XXVIII myosins consist of an IQ motif, a short coiled-coil region, and an SH2 domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments.

class XVIII myosin, motor domain; Many members of this class contain a N-terminal PDZ domain which is commonly found in proteins establishing molecular complexes. The motor domain itself does not exhibit ATPase activity, suggesting that it functions as an actin tether protein. It also has two IQ domains that probably bind light chains or related calmodulins and a C-terminal tail with two sections of coiled-coil domains, which are thought to mediate homodimerization. The function of these myosins are largely unknown. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments.

class XX myosin, motor domain; These class 20 myosins are primarily insect myosins with such members as Drosophila, Daphnia, and mosquitoes. These myosins contain a single IQ motif in the neck region. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class XVI myosin, motor domain; These XVI type myosins are also known as Neuronal tyrosine-phosphorylated phosphoinositide-3-kinase adapter 3/NYAP3. Myo16 is thought to play a regulatory role in cell cycle progression and has been recently implicated in Schizophrenia. Class XVI myosins are characterized by an N-terminal ankyrin repeat domain and some with chitin synthase domains that arose independently from the ones in the class XVII fungal myosins. They bind protein phosphatase 1 catalytic subunits 1alpha/PPP1CA and 1gamma/PPP1CC. Human Myo16 interacts with ACOT9, ARHGAP26 and PIK3R2 and with components of the WAVE1 complex, CYFIP1 and NCKAP1. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force.

20-108 1.68e-17

class XXIII myosin, motor domain; These myosins are predicted to have a neck region with 1-2 IQ motifs and a single MyTH4 domain in its C-terminal tail. The lack of a FERM domain here is odd since MyTH4 domains are usually found alongside FERM domains where they bind to microtubules. At any rate these Class XXIII myosins are still proposed to function in the apicomplexan microtubule cytoskeleton. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments.

Myo21, unlike other myosin proteins, contains UBA-like protein domains and has no structural or functional relationship with the myosins present in other organisms possessing cilia or flagella. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. They have diverse tails with IQ, WW, PX, and Tub domains.

class myosin, motor domain; Class XXXIII myosins have variable numbers of IQ domain and 2 tandem ANK repeats that are separated by a PH domain. The myosin classes XXX to XXXIV contain members from Phytophthora species and Hyaloperonospora parasitica. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.
