CC -!- FUNCTION: Appears to play a crucial role in the insertion of secretory
CC and membrane polypeptides into the ER. It is required for assembly of
CC membrane and secretory proteins. Found to be tightly associated with
CC membrane-bound ribosomes, either directly or through adaptor proteins
CC (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Heterotrimeric complex composed of SEC61-alpha, SEC61-beta and
CC SEC61-gamma. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the SecY/SEC61-alpha family. {ECO:0000305}.
