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.,similarity:Belongs to the secY/SEC61-alpha family.,subunit:Heterotrimeric complex composed of SEC61-alpha, SEC61-beta and SEC61-gamma.,
Endoplasmic reticulum membrane ; Multi-pass membrane protein .
