CC   -!- FUNCTION: Involved in protein export. The function of the beta subunit
CC       is unknown, but it may be involved in stabilization of the trimeric
CC       complex (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the protein translocase complex. Heterotrimer
CC       consisting of alpha (SecY), beta (SecG) and gamma (SecE) subunits. Can
CC       form oligomers of the heterotrimer (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass membrane
CC       protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the SEC61-beta family. {ECO:0000305}.
