Also known as: ACR1
Summary: 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).

What's a GeneRIF?

An expanded cell wall damage signaling network is comprised of the transcription factors Rlm1 and Sko1 in Candida albicans.
Title: An expanded cell wall damage signaling network is comprised of the transcription factors Rlm1 and Sko1 in Candida albicans.
Sko1 is sumoylated at Lys 567 and, although many of its targets are osmoresponse genes, the level of Sko1 sumoylation is not stress-regulated and the modification does not depend or impinge on its phosphorylation by the osmostress kinase Hog1.
Title: Sumoylation of DNA-bound transcription factor Sko1 prevents its association with nontarget promoters.
The results thus provide evidence that Plc1p and inositol polyphosphates affect derepression of Sko1p-Ssn6p-Tup1p-controlled genes by a mechanism that involves recruitment of the SAGA complex and TATA-binding protein.
Title: Plc1p is required for SAGA recruitment and derepression of Sko1p-regulated genes.
our results suggest that Sko1 operates a transcriptional network upon osmotic stress, which involves other specific transcription factors and a phosphatase that regulates the key component of the signal transduction pathway.
Title: Genomewide identification of Sko1 target promoters reveals a regulatory network that operates in response to osmotic stress in Saccharomyces cerevisiae.
