EMC7_HUMAN / Q9NPA0 ER membrane protein complex subunit 7 from Homo sapiens (Human) (see 6 papers)
Aligns to 56:168 / 242 (46.7%), covers 99.2% of PF09430, 136.9 bits

• 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:30415835, PubMed:29809151, PubMed:29242231, PubMed:32459176, PubMed:32439656). Preferentially accommodates proteins with transmembrane domains that are weakly hydrophobic or contain destabilizing features such as charged and aromatic residues (PubMed:30415835, PubMed:29809151, PubMed:29242231). Involved in the cotranslational insertion of multi-pass membrane proteins in which stop-transfer membrane-anchor sequences become ER membrane spanning helices (PubMed:30415835, PubMed:29809151). It is also required for the post-translational insertion of tail-anchored/TA proteins in endoplasmic reticulum membranes (PubMed:29809151, PubMed:29242231). 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).
  subunit: Component of the ER membrane protein complex (EMC).

NOMO1_HUMAN / Q15155 BOS complex subunit NOMO1; Nodal modulator 1; pM5 protein from Homo sapiens (Human) (see 5 papers)
Aligns to 339:409 / 1222 (5.8%), covers 46.7% of PF09430, 79.5 bits

• function: Component of the multi-pass translocon (MPT) complex that mediates insertion of multi-pass membrane proteins into the lipid bilayer of membranes (PubMed:36261522, PubMed:32820719). The MPT complex takes over after the SEC61 complex: following membrane insertion of the first few transmembrane segments of proteins by the SEC61 complex, the MPT complex occludes the lateral gate of the SEC61 complex to promote insertion of subsequent transmembrane regions (PubMed:36261522).
  subunit: Component of the back of Sec61 (BOS) complex, composed of NCLN/Nicalin, NOMO (NOMO1, NOMO2 or NOMO3) and TMEM147 (PubMed:20538592, PubMed:36261522). The BOS complex is part of the multi-pass translocon (MPT) complex, composed of three subcomplexes, the GEL complex (composed of RAB5IF/OPTI and TMCO1), the BOS complex (composed of NCLN/Nicalin, NOMO and TMEM147) and the PAT complex (composed of WDR83OS/Asterix and CCDC47) (PubMed:36261522, PubMed:32820719). The MPT complex associates with the SEC61 complex (PubMed:32820719, PubMed:36261522). Due to the strong similarity between NOMO1, NOMO2 and NOMO3, similar interaction pattern probably occur for the three gene copies (PubMed:20538592, PubMed:32820719).

NOMO2_HUMAN / Q5JPE7 BOS complex subunit NOMO2; Nodal modulator 2; pM5 protein 2 from Homo sapiens (Human) (see 5 papers)
