 1-188 3.72e-140

ATPase-like domain of the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily; The ASKHA superfamily, also known as actin-like ATPase domain superfamily, includes acetate and sugar kinases, heat-shock cognate 70 (Hsp70) and actin family proteins. They either function as conformational hydrolases (e.g. Hsp70, actin) that perform simple ATP hydrolysis, or as metabolite kinases (e.g. glycerol kinase) that catalyze the transfer of a phosphoryl group from ATP to their cognate substrates. Both activities depend on the presence of specific metal cations. ASKHA superfamily members share a common core fold that includes an actin-like ATPase domain consisting of two subdomains (denoted I _ II) with highly similar ribonuclease (RNase) H-like folds. The fold of each subdomain is characterized by a central five strand beta-sheet and flanking alpha-helices. The two subdomains form an active site cleft in which ATP binds at the bottom. Another common feature of ASKHA superfamily members is the coupling of phosphoryl-group transfer to conformational rearrangement, leading to domain closure. Substrate binding triggers protein motion.

nucleotide-binding domain (NBD) of actin, actin-related proteins T1-T3 (Arp-T1-3), and similar proteins; The family includes actin and human actin-related proteins T1, T2, and T3. Actin is a ubiquitous protein involved in the formation of filaments that are major components of the cytoskeleton. It is a highly dynamic structural protein network involved in processes such as cell contraction, cell motility, vesicle trafficking, intracellular organization, cytokinesis, endocytosis and apoptosis. Arp-T1, encoded by ACTRT1/ARPT1 gene expressed in testis, negatively regulates the Hedgehog (SHH) signaling, binds to the promoter of the SHH signaling mediator, GLI1, and inhibits its expression. Arp-T2 (also called actin-related protein M2; encoded by ACTRT2/ARPM2 gene expressed in testis and various other cell types) and Arp-T3 (also called actin-related protein M1; encoded by ACTRT3/ARPM1 gene expressed in all tested human tissues) play general roles in the organization of the cytoskeleton like other cytoplasmic actin-related proteins.

 2-189 5.03e-38

nucleotide-binding domain (NBD) of actin-related protein 1 (Arp1) and similar proteins; Arp1, also called centractin, actin-like protein, alpha-centractin, actin-RPV, or centrosome-associated actin homolog, may be a component of a multi-subunit centrosomal complex involved in microtubule-based vesicle motility. In yeast, actin-related protein is essential for viability and is associated with the centrosome. In vertebrates, Arp1 is a core component of the dynactin complex which assists cytoplasmic dynein by increasing its processivity and by regulation of its cargo binding. The dynactin complex is required for the spindle translocation late in anaphase and is involved in a cell wall synthesis checkpoint. ARP1 forms the backbone filament of the dynactin rod structure and serves as the scaffold for the remaining subunits. It is required for proper orientation of the mitotic spindle. Arp1 is the only actin-related protein known to form actin-like filaments. Human Arp1/centractin is encoded by the ACTR1A gene.

 1-189 4.57e-34

nucleotide-binding domain (NBD) of actin-related protein2 (Arp2) and similar proteins; Arp2, also called actin-like protein 2, is the ATP-binding component of the Arp2/3 complex, a multiprotein complex that mediates actin polymerization upon stimulation by nucleation-promoting factor (NPF). The Arp2/3 complex is comprised of 7 proteins (Arp2, Arp3, and five conserved proteins, ARPC1-5). It generates cytoplasmic branched filaments networks, by promoting nucleation of actin filaments as 70 degrees branches on the side of older filaments. It is activated, by simultaneously binding to a pre-existing filament and a nucleation promoting factor plus an actin monomer. Daughter branches subsequently detach/debranch from the mother filament. Its Arp2 and Arp3 subunits must be loaded with ATP for it to initiate the assembly of branched actin filaments. ATP hydrolysis may be required for branch initiation or debranching. The Arp2/3 complex is also found in the nucleus where it plays a role in promoting de novo actin polymerization and in RNA polymerase II-dependent transcription. This may in part be through regulating nuclear actin polymerization in a way like its function in the cytoplasm. Human Arp2 is encoded by the ACTR2 gene.

nucleotide-binding domain (NBD) of actin and similar proteins; Actin is a ubiquitous protein involved in the formation of filaments that are major components of the cytoskeleton. It is a highly dynamic structural protein network involved in processes such as cell contraction, cell motility, vesicle trafficking, intracellular organization, cytokinesis, endocytosis and apoptosis. Actin is a monomeric globular protein (G-actin) that reversibly polymerizes to form filaments (F-actin). Each actin protomer binds one molecule of ATP and either calcium or magnesium ions. At low salt concentrations, actin exists as a monomer, and as the salt concentration rises F-actin forms, with the consequent hydrolysis of ATP. F-actin assembly is in constant flux with G-actin association occurring at the barbed end (+) and its disassociation at the pointed end (-). Actin monomers that have been released from the pointed end can be reused, if the ADP is exchanged for ATP. F-actin filaments can assemble into higher order structures, for example branched F-actin, and stress fibers. Actin binding proteins regulate actin filament dynamics by a range of functions including actin severing, depolymerizing, capping, stabilizing and de novo actin polymerization. Actins interaction with myosin is the basis of muscular contraction and many aspects of cell motility. In vertebrates there are three main groups of actin isoforms, alpha, beta and gamma. The alpha actins found in muscle tissues are a major constituent of the contractile apparatus. The beta and gamma actins co-exist in most cell types as components of the cytoskeleton and as mediators of internal cell motility. In plants there are many isoforms which are probably involved in a variety of functions such as cytoplasmic streaming, cell shape determination, tip growth, graviperception, cell wall deposition, etc.

Each actin protomer binds one molecule of ATP and either calcium or magnesium ions. F-actin filaments form with the consequent hydrolysis of ATP. Some actin-related proteins (Arps) have roles in cytoskeletal functions, such as actin polymerization (Arp2/3) and dynein motor activity (Arp1). Both conventional actin and specific Arps have been implicated in chromatin remodeling and/or transcription regulation. The actin/ARP family belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of the actin-like protein 7 (ACTL7)-like family; The ACTL7-like family includes ACTL7A, ACTL7B and ACTL9 (also known as ACTL7C). In mammalian, ACTL7A is expressed in a wide variety of adult tissues, while the ACTL7B is expressed in spermatids through the elongation phase of spermatid development. ACTL7A, also called actin-like-7-alpha, or T-ACTIN-2 in mouse, may play an important role in formation and fusion of Golgi-derived vesicles during acrosome biogenesis. ACTL7B, also called actin-like-7-beta, acts as a key regulator of spermiogenesis that is required for male fertility. ACTL9 is a testis-specific protein that plays an important role in fusion of proacrosomal vesicles and perinuclear theca formation.

 1-187 3.37e-21

nucleotide-binding domain (NBD) of the actin-related protein 4 (Arp4)-like subfamily; The Arp4-like subfamily includes Arp4, also called actin-like protein 4, from fungi and plants. Saccharomyces cerevisiae Arp4 acts synergistically with Arp8 to depolymerize F-actin; it binds ATP, but unlike conventional actin, does not form filaments. It is a component of the NuA4 histone acetyltransferase complex, the chromatin-remodeling INO80 complex and the SWR1 chromatin remodeling complex. Arabidopsis thaliana Arp4 is involved in several developmental processes including organization of plant organs, flowering time, anther development, flower senescence and fertility, probably by regulating the chromatin structure. This family also includes human homologs of yeast and plant, which are actin-like protein 6A (encoded by the ACTL6A gene; also known as ArpNbeta, 53 kDa BRG1-associated factor A/BRG1-associated factor 53A/BAF35A, and INO80 complex subunit K/INO80K) and actin-like protein 6B (encoded by the ACTL6B gene; also known as ArpNalpha, 53 kDa BRG1-associated factor B/BRG1-associated factor 53B/BAF35B). ACTL6A and ACTL6B are involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). They are components of numerous complexes with chromatin remodeling and histone acetyltransferase activity. ACTL6A is also a putative core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair. Schizosaccharomyces pombe actin-related protein 42 (Arp42) is also included in this family. It is also a component of SWI/SNF and RSC complexes.

 29-188 2.34e-15

nucleotide-binding domain (NBD) of actin-related protein6 (Arp6) and similar proteins; Arp6, also called actin-like protein 6, is required for formation and/or maintenance of proper nucleolar structure and function, plays a dual role in the regulation of ribosomal DNA (rDNA) transcription. In the presence of high glucose, Arp6 maintains active rDNA transcription through H2A.Z deposition and under glucose starvation, it is required for the repression of rDNA transcription, and this function may be independent of H2A.Z. Arp6 is also required for telomere silencing in both fission and budding yeast. It is a component of the budding yeast and Arabidopsis SWR1 complex (SWR1C) and the human SWI2/SNF2-related CBP activator protein (SRCAP) chromatin remodeling complexes which catalyze the exchange of the histone H2A with the H2AZ. Drosophila Arp6 colocalizes with HP1 (heterochromatin protein 1) in the pericentric heterochromatin, and vertebrate Arp6 also interacts with HP1. Human Arp6 is encoded by the ACTR6 gene. Arabidopsis thaliana ACTIN RELATED PROTEIN 6/EARLY IN SHORT DAYS 1/SUPPRESSOR OF FRIGIDA 3 (encoded by ARP6/ESD1/SUF3) participates in regulating several leaf and flower development stages. It is needed for Flowering locus C (FLC, the master repressor of flowering) and FLC-like gene expression in the shoot and root apex, and for the activity of the floral repressor pathway.

nucleotide-binding domain (NBD) of Saccharomyces cerevisiae actin-related protein 9 (Arp9) and similar proteins; Saccharomyces cerevisiae Arp9, also called actin-like protein 9, chromatin structure-remodeling complex protein ARP9, or SWI/SNF complex component ARP9, is a component of the chromatin structure remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning. It is also part of the SWI/SNF complex, an ATP-dependent chromatin remodeling complex, which is required for the positive and negative regulation of gene expression of many genes. Arp9 forms a stable heterodimer with Arp7 protein in both the RSC and SWI/SNF chromatin-remodeling complexes. It has been suggested that this dimer functions as a module with DNA bending proteins, to achieve correct architecture and facilitate complex-complex interactions. Fission yeast SWI/SNF and RSC complexes do not contain Arp7 and Arp8, but instead contain Arp9 and Arp42.

nucleotide-binding domain (NBD) of actin-related protein5 (Arp5) and similar proteins; Arp5, also called actin-like protein 5, may act as a core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair. It is involved in DNA double-strand break repair and UV-damage excision repair. Human Arp5 is encoded by the ACTR5 gene. Arabidopsis thaliana ARP5 (AtARp5) is a ubiquitously expressed nuclear protein involved in DNA repair and required for multicellular development of all organs. AtARp5 may be part of other chromatin remodeling machines in addition to INO80.

 35-110 3.74e-05

nucleotide-binding domain (NBD) of the actin-related protein 8 (Arp8)-like subfamily; The Arp8-like family includes Arp8, also called actin-like protein 8, from vertebrates and fungi. Human Arp8 is encoded by the ACTR8 gene and is also known as INO80 complex subunit N. It plays an important role in the functional organization of mitotic chromosomes. Arp8 exhibits low basal ATPase activity, and is unable to polymerize. It is probably a core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication, and probably DNA repair. it is required for the recruitment of INO80 (and probably the INO80 complex) to sites of DNA damage. Arp8 strongly prefers nucleosomes and H3-H4 tetramers over H2A-H2B dimers, suggesting it may act as a nucleosome recognition module within the complex. This subfamily also contains Arabidopsis thaliana Arp9.

nucleotide-binding domain (NBD) of the PilM-like domain family; The PilM-like family includes type IV pilus inner membrane component PilM, cell division protein FtsA, and ethanolamine utilization protein EutJ. PilM is an inner membrane component of the type IV (T4S) secretion system that plays a role in surface and host cell adhesion, colonization, biofilm maturation, virulence, and twitching, a form of surface-associated motility. FtsA is an essential cell division protein that assists in the assembly of the Z ring. It may serve as the principal membrane anchor for the Z ring. It is also required for the recruitment to the septal ring of the downstream cell division proteins FtsK, FtsQ, FtsL, FtsI and FtsN. EutJ may protect ethanolamine ammonia-lyase (EAL, eutB-eutC) from inhibition. It may also function in assembling the bacterial microcompartment and/or in refolding EAL, suggesting it may have chaperone activity. Members in PilM-like family belong to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily of phosphotransferases, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.
