General annotation (Comments)

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 adaptor proteins.

Subunit structure

Heterotrimeric complex composed of SEC61-alpha, SEC61-beta and SEC61-gamma.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Sequence similarities

Belongs to the SecY/SEC61-alpha family.
