Protein: SNF1 protein kinase subunit beta-1 (SNF1-interacting protein 1) (P32578)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Beta subunit of the SNF1 kinase complex, which is required for transcriptional, metabolic, and developmental adaptations in response to glucose limitation. Has a structural role, mediating heterotrimer formation, and a regulatory role, defining carbon source-regulated subcellular location and substrate specificity of the SNF1 kinase complex. Promotes the PKA-regulated relocalization of the SNF1 kinase complex to the vacuolar membrane in response to various types of carbon stress.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:11331606, ECO:0000269|PubMed:14966266}. Vacuole membrane {ECO:0000269|PubMed:11331606, ECO:0000269|PubMed:14966266}; Peripheral membrane protein {ECO:0000269|PubMed:11331606, ECO:0000269|PubMed:14966266}; Cytoplasmic side {ECO:0000269|PubMed:11331606, ECO:0000269|PubMed:14966266}. Note=Resides in the cytosol during growth in glucose and relocalizes to the vacuolar membrane in response to carbon stress. {ECO:0000269|PubMed:14966266}.
