RA Finke K., Prehn S., Hartmann E.;
RT "Sec61 alpha isoforms.";
RL Submitted (FEB-2001) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Plays a crucial role in the insertion of secretory and
CC membrane polypeptides into the ER. Required for assembly of membrane
CC and secretory proteins. Tightly associated with membrane-bound
CC ribosomes, either directly or through adapter proteins (By similarity).
CC Plays a role in pronephric kidney tubule development (By similarity).
CC {ECO:0000250, ECO:0000250|UniProtKB:P61620}.
CC -!- SUBUNIT: Heterotrimeric complex composed of SEC61-alpha, SEC61-beta and
CC SEC61-gamma. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P61619}; Multi-pass membrane protein
CC {ECO:0000305}. Note=Localizes exclusively in granular structures in the
CC endoplasmic reticulum (ER). {ECO:0000250|UniProtKB:P61619}.
CC -!- SIMILARITY: Belongs to the SecY/SEC61-alpha family. {ECO:0000305}.
