Subcellular location

Subcellular Location:
Endoplasmic reticulum membrane

Function

Function:
Appears to play a crucial role in the insertion of secretory and membrane polypeptides into the ER. It is required for assembly of membrane and secretory proteins. Found to be tightly associated with membrane-bound ribosomes, either directly or through adaptor proteins (By similarity).
