Subcellular location

Subcellular Location:
Endoplasmic reticulum membrane; Multi-pass membrane protein.

Function

Function:
Plays a crucial role in the insertion of secretory and membrane polypeptides into the ER. Required for assembly of membrane and secretory proteins. Tightly associated with membrane-bound ribosomes, either directly or through adapter proteins.
