218-439 1.18e-158

MIR domain, beta-trefoil fold, found in inositol 1,4,5-trisphosphate receptor type 2 (ITPR2) and similar proteins; ITPR2, also called IP3 receptor isoform 2 (IP3R 2), or InsP3R2, or type 2 inositol 1,4,5-trisphosphate receptor, or type 2 InsP3 receptor, is a key regulator for the activity of calcium ion transmembrane transportation, which plays a critical role in cell cycle and proliferation. It is a receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium. This release is regulated by cAMP both dependently and independently of cAMP-dependent protein kinase (PKA). ITPR2 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

5-228 8.06e-98

Inositol 1,4,5-trisphosphate/ryanodine receptor; This domain corresponds to the ligand binding region on inositol 1,4,5-trisphosphate receptor, and the N terminal region of the ryanodine receptor. Both receptors are involved in Ca2+ release. They can couple to the activation of neurotransmitter-gated receptors and voltage-gated Ca2+ channels on the plasma membrane, thus allowing the endoplasmic reticulum discriminate between different types of neuronal activity.

218-439 1.18e-158

MIR domain, beta-trefoil fold, found in inositol 1,4,5-trisphosphate receptor type 2 (ITPR2) and similar proteins; ITPR2, also called IP3 receptor isoform 2 (IP3R 2), or InsP3R2, or type 2 inositol 1,4,5-trisphosphate receptor, or type 2 InsP3 receptor, is a key regulator for the activity of calcium ion transmembrane transportation, which plays a critical role in cell cycle and proliferation. It is a receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium. This release is regulated by cAMP both dependently and independently of cAMP-dependent protein kinase (PKA). ITPR2 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

MIR domain, beta-trefoil fold, found in the family of inositol 1,4,5-trisphosphate receptor (ITPR); Inositol 1,4,5 trisphosphate receptors (ITPRs) are a family of endoplasmic reticulum Ca2+ channels essential for the control of intracellular Ca2+ levels in virtually every mammalian cell type. Calcium-mediated signaling through ITPRs is essential for the regulation of numerous physiological processes, including fertilization, muscle contraction, apoptosis, secretion, and synaptic plasticity. The ITPR family includes three isoforms (ITPR1, ITPR2 and ITPR3), which can control different cellular processes due to their unique biophysical properties, subcellular localization, and tissue distribution. ITPRs contain an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

Inositol 1,4,5-trisphosphate/ryanodine receptor; This domain corresponds to the ligand binding region on inositol 1,4,5-trisphosphate receptor, and the N terminal region of the ryanodine receptor. Both receptors are involved in Ca2+ release. They can couple to the activation of neurotransmitter-gated receptors and voltage-gated Ca2+ channels on the plasma membrane, thus allowing the endoplasmic reticulum discriminate between different types of neuronal activity.

231-439 8.16e-26

MIR domain, beta-trefoil fold, found in Caenorhabditis elegans inositol 1,4,5-trisphosphate receptor Itr-1 and similar proteins; Itr-1, also called IP3 receptor, or IP3R, or InsP3R, or LET-23 fertility effector 1, is a receptor for inositol 1,4,5-trisphosphate, a second messenger that regulates intracellular calcium homeostasis. It binds in vitro to both inositol 1,4,5-trisphosphate (1,4,5-InsP3) and inositol 2,4,5-trisphosphate (2,4,5-InsP3) with high affinity. It can also bind inositol 1,3,4,5-tetrakisphosphate (1,3,4,5-InsP4) and inositol 4,5-bisphosphate (4,5-InsP2), but with lower affinity. Itr-1 acts as a timekeeper/rhythm generator via calcium signaling, affecting the defecation cycle and pharyngeal pumping. It affects normal hermaphrodite and male fertility as a participant in intracellular signaling by acting downstream of let-23/lin-3 which regulates ovulation, spermathecal valve dilation and male mating behavior. It plays an important role in early embryonic development. It controls epidermal cell migration and may also regulate filopodial protrusive activity during epithelial morphogenesis. Itr-1 functions as a component of inositol trisphosphate (IP3)-mediated downstream signaling pathways that controls amphid sensory neuronal (ASH)-mediated response to nose touch and benzaldehyde, but no other ASH-mediated responses. Itr-1 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

MIR domain, beta-trefoil fold, found in ryanodine receptor 3 (RyR3) and similar proteins; RyR3, also called RYR-3, or brain ryanodine receptor-calcium release channel, or brain-type ryanodine receptor, or type 3 ryanodine receptor, is a calcium channel that plays a role in cellular calcium signaling. It mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm in muscle and thereby plays a role in triggering muscle contraction. It also mediates Ca(2+)-induced Ca(2+) release from the endoplasmic reticulum in non-muscle cells. RYR-3 forms homotetramer and also forms heterotetramer with RYR-2. RYR-3 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

It can also mediate the release of Ca(2+) from intracellular stores in neurons, and may thereby promote prolonged Ca(2+) signaling in the brain. It is required for normal embryonic development of muscle fibers and skeletal muscle, as well as for normal heart morphogenesis, skin development and ossification during embryogenesis. RYR-1 forms homotetramer and can also form heterotetramers with RYR-2. RYR-1 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

The family includes three closely homologous proteins, RyR1, RyR2 and RyR3. RyR1 is present in skeletal muscle; RyR2 is in heart muscle; and RyR3 is expressed at low levels in many tissues including brain, smooth muscle, and slow-twitch skeletal muscle. RYR2 is the major cellular mediator of calcium-induced calcium release (CICR) in animal cells. RyR1 and RyR2 release Ca2+ from the ER in response to excitation of muscle membranes to promote muscle contraction. RYR3 is involved in force production and calcium handling in extraocular muscle. RYRs contain an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

MIR domain, beta-trefoil fold, found in ryanodine receptor 2 (RyR2) and similar proteins; RyR2, also called RYR-2, or cardiac muscle ryanodine receptor-calcium release channel, or cardiac muscle ryanodine receptor, or type 2 ryanodine receptor, is a calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering cardiac muscle contraction. Aberrant channel activation can lead to cardiac arrhythmia. In cardiac myocytes, calcium release is triggered by increased Ca(2+) levels due to activation of the L-type calcium channel CACNA1C. The calcium channel activity of RYR-2 is modulated by formation of heterotetramers with RYR-3. RYR-2 is required for cellular calcium ion homeostasis. it plays an essential role in embryonic heart development. RYR-2 forms homotetramer and also forms heterotetramers with RYR-1 and RYR-3. RYR-2 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.
