S.cerevisiae - Yeastract

Gene Ontology Information

Protein Name	Xbp1p
Description	Transcriptional repressor; binds promoter sequences of cyclin genes, CYS3, and SMF2; not expressed during log phase of growth, but induced by stress or starvation during mitosis, and late in meiosis; represses 15% of all yeast genes as cells transition to quiescence; important for maintaining G1 arrest and for longevity of quiescent cells; member of Swi4p/Mbp1p family; phosphorylated by Cdc28p; relative distribution to nucleus increases upon DNA replication stress
GO Terms: Biological Process	level 5: cellular response to oxidative stress level 6: asparagine catabolic process level 9: negative regulation of transcription by RNA polymerase II level 10: positive regulation of histone deacetylation
GO Terms: Molecular Function	level 3: DNA-binding transcription factor activity level 4: DNA-binding transcription factor activity, RNA polymerase II-specific level 5: DNA binding level 6: sequence-specific DNA binding level 6: asparaginase activity
GO Terms: Cellular Component	level 3: periplasmic space level 3: cytoplasm level 5: nucleus
