Recombinant Human ER membrane protein complex subunit 10 (EMC10), partial

Function

Part of the endoplasmic reticulum membrane protein complex (EMC) that enables the energy-independent insertion into endoplasmic reticulum membranes of newly synthesized membrane proteins (PubMed:29242231, PubMed:29809151, PubMed:30415835, PubMed:32439656, PubMed:32459176). Preferentially accommodates proteins with transmembrane domains that are weakly hydrophobic or contain destabilizing features such as charged and aromatic residues (PubMed:29242231, PubMed:29809151, PubMed:30415835). Involved in the cotranslational insertion of multi-pass membrane proteins in which stop-transfer membrane-anchor sequences become ER membrane spanning helices (PubMed:29809151, PubMed:30415835). It is also required for the post-translational insertion of tail-anchored/TA proteins in endoplasmic reticulum membranes (PubMed:29242231, PubMed:29809151). By mediating the proper cotranslational insertion of N-terminal transmembrane domains in an N-exo topology, with translocated N-terminus in the lumen of the ER, controls the topology of multi-pass membrane proteins like the G protein-coupled receptors (PubMed:30415835). By regulating the insertion of various proteins in membranes, it is indirectly involved in many cellular processes (Probable). Promotes angiogenesis and tissue repair in the heart after myocardial infarction. Stimulates cardiac endothelial cell migration and outgrowth via the activation of p38 MAPK, PAK and MAPK2 signaling pathways (PubMed:28931551)

Disease Association

Neurodevelopmental disorder with dysmorphic facies and variable seizures (NEDDFAS) : An autosomal recessive disorder characterized by global developmental delay apparent in early childhood, mildly impaired intellectual development, speech delay, behavioral abnormalities, and non-specific dysmorphic facial features. Some patients may have seizures, brain imaging abnormalities, mild skeletal defects, and renal abnormalities. [The disease is caused by variants affecting the gene represented in this entry]

Tissue Specificity

Present in serum (at protein level). Increased expression seen in the left ventrice after myocardial infarction (at protein level). Expressed in the pituitary gland. Expressed in brain (PubMed:33531666)
