Protein: BOS complex subunit NOMO3 (P69849)
Organism: complex subunit NOMO3 {ECO:0000305};
Function: Component of the multi-pass translocon (MPT) complex that mediates insertion of multi-pass membrane proteins into the lipid bilayer of membranes. 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
Subcellular location: Endoplasmic reticulum membrane; Single-pass type I membrane protein
