CC -!- FUNCTION: Beta subunit of the SNF1 kinase complex, which is required
CC for transcriptional, metabolic, and developmental adaptations in
CC response to glucose limitation. Has a structural role, mediating
CC heterotrimer formation, and a regulatory role, defining carbon source-
CC regulated subcellular location and substrate specificity of the SNF1
CC kinase complex. Promotes the PKA-regulated relocalization of the SNF1
CC kinase complex to the vacuolar membrane in response to various types of
CC carbon stress (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the SNF1 kinase complex, a heterotrimeric complex
CC composed of the catalytic alpha subunit SNF1, one of the three related
CC beta subunits SIP1, SIP2 or GAL83, and the regulatory gamma subunit
CC SNF4. The beta subunit serves as a bridge between the catalytic and the
CC regulatory subunit. Interacts (via KIS domain) with SNF1. Interacts
CC (via ASC domain) with SNF4 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Vacuole membrane
CC {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic
CC side {ECO:0000250}. Note=Resides in the cytosol during growth in
CC glucose and relocalizes to the vacuolar membrane in response to carbon
CC stress. {ECO:0000250}.
CC -!- PTM: Phosphorylated by SNF1 in vitro. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the 5'-AMP-activated protein kinase beta subunit
CC family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=EDN60749.1; Type=Erroneous initiation; Evidence={ECO:0000305};
