Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; mitogen-activated protein kinase binding activity; and transcription corepressor activity. Involved in cellular response to osmotic stress; negative regulation of transcription by RNA polymerase II; and positive regulation of transcription by RNA polymerase II. Located in cytosol and nucleus. Orthologous to human ATF2 (activating transcription factor 2); ATF7 (activating transcription factor 7); and CREB5 (cAMP responsive element binding protein 5).
SGD Description
Basic leucine zipper transcription factor of the ATF/CREB family; forms a complex with Tup1p and Cyc8p to both activate and repress transcription; cytosolic and nuclear protein involved in osmotic and oxidative stress responses
