Summary: Enables histone deacetylase binding activity; transcription coactivator activity; and transcription corepressor activity. Involved in several processes, including negative regulation of dipeptide transport; regulation of fatty acid biosynthetic process; and regulation of transcription by RNA polymerase II. Located in nucleus. Part of transcription repressor complex. Human ortholog(s) of this gene implicated in several diseases, including Kabuki syndrome; Stolerman neurodevelopmental syndrome; gastrointestinal system cancer (multiple); lung carcinoma (multiple); and triple-receptor negative breast cancer. Orthologous to several human genes including KDM6A (lysine demethylase 6A) and KDM6B (lysine demethylase 6B). [provided by Alliance of Genome Resources, Dec 2024]

Study provides clear evidence of the functions of the Tup1p and Cyc8p regulators in biofilm colony formation. Cyc8p itself is a repressor of FLO11 gene expression and of the formation of the structured architecture of colony biofilms, whereas Tup1p counteracts Cyc8p, being a positive regulator of FLO11 expression and colony complexity.

corepressors may be recruited not only by repressors but also by activators such as Ino2. Indeed, we could demonstrate direct interaction of Ino2 with Sin3 and Cyc8. The Opi1 repressor interaction domain within Ino2 is also able to contact Sin3 and Cyc8.

Preferred Names: transcription regulator CYC8

NP_009670.3

Transcriptional regulator; functions primarily as a transcriptional co-repressor with Tup1p but can also function as a transcriptional co-activator with Tup1p that recruits the SWI/SNF and SAGA complexes to promoters; target genes may be uniquely repressed by Cyc8p or Tup1p, subject to redundant repression, or in some cases de-repression of target genes in a cyc8 mutant is dependent upon TUP1 and vice versa; can form the prion [OCT+]
