MIR domain, beta-trefoil fold, found in protein O-mannosyl-transferase 2 (POMT2) and similar proteins; POMT2 (EC 2.4.1.109), also called dolichyl-phosphate-mannose--protein mannosyltransferase 2, is a novel member of the PMT protein O-mannosyltransferase family specifically localized to the acrosome of mammalian spermatids. POMT2 transfers mannosyl residues to the hydroxyl group of serine or threonine residues. Coexpression of both POMT1 and POMT2 is necessary for enzyme activity, expression of either POMT1 or POMT2 alone is insufficient. It is essentially dedicated to O-mannosylation of alpha-DAG1 and few other proteins but not of cadherins and protocaherins. POMT2 contains a 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. : Pssm-ID: 467753 [Multi-domain] Cd Length: 183 Bit Score: 365.47 E-value: 4.03e-123

Dolichyl-phosphate-mannose-protein mannosyltransferase; This is a family of Dolichyl-phosphate-mannose-protein mannosyltransferase proteins EC:2.4.1.109. These proteins are responsible for O-linked glycosylation of proteins, they catalyze the reaction:- Dolichyl phosphate D-mannose + protein <=> dolichyl phosphate + O-D-mannosyl-protein. Also in this family is the Drosophila rotated abdomen protein which is a putative mannosyltransferase. This family appears to be distantly related to pfam02516 (A Bateman pers. obs.). This family also contains sequences from ArnTs (4-amino-4-deoxy-L-arabinose lipid A transferase). They catalyze the addition of 4-amino-4-deoxy-l-arabinose (l-Ara4N) to the lipid A moiety of the lipopolysaccharide. This is a critical modification enabling bacteria (e.g. Escherichia coli and Salmonella typhimurium) to resist killing by antimicrobial peptides such as polymyxins. Members such as Swiss:O52327 are predicted to have 12 trans-membrane regions. The N-terminal portion of these proteins is hypothesized to have a conserved glycosylation activity which is shared between distantly related oligosaccharyltransferases ArnT and PglB families. : Pssm-ID: 396786 [Multi-domain] Cd Length: 245 Bit Score: 266.10 E-value: 8.10e-84

SDF-2 is a secretory protein involved in multiple endoplasmic reticulum (ER) functions, including the misfolded protein catabolic process, protein glycosylation, and ER protein quality control. SDF2L1, also called PWP1-interacting protein 8, is an endoplasmic reticulum (ER)-localized protein that plays a role in ER-associated degradation (ERAD) of misfolded proinsulin in pancreatic beta-cells. It is a component of the endoplasmic reticulum (ER) chaperone complex and interacts with alpha- and beta-defensins. SDF2L1 may also act as a tumor suppressor that play an important role in a variety of cancers, such as breast cancer and ovarian cancer. AtSDF2, also called SDF2-like protein, acts as crucial component of the unfolded protein response (UPR) in Arabidopsis thaliana. It is involved in the endoplasmic reticulum (ER) protein quality control and unfolded protein response. It may be involved in the quality control of glycoproteins. AtSDF2 forms a complex in the ER with ERDJ3B and MED37A/BIP1 which is required for the proper accumulation and function of the surface-exposed leucine-rich repeat receptor kinases EFR involved in pathogen-associated molecular pattern (PAMP) triggered immunity.

MIR domain, beta-trefoil fold, found in Arabidopsis thaliana stromal cell-derived factor 2-like protein (AtSDF2) and similar proteins; AtSDF2, also called SDF2-like protein, acts as a crucial component of the unfolded protein response (UPR) in Arabidopsis thaliana. It is involved in the endoplasmic reticulum (ER) protein quality control and unfolded protein response. It may be involved in the quality control of glycoproteins. AtSDF2 forms a complex in the ER with ERDJ3B and MED37A/BIP1 which is required for the proper accumulation and function of the surface-exposed leucine-rich repeat receptor kinases EFR involved in pathogen-associated molecular pattern (PAMP) triggered immunity. AtSDF2 contains a 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 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.
