Summary: Enables several functions, including RNA polymerase II-specific DNA-binding transcription factor binding activity; chromatin binding activity; and transcription corepressor activity. Involved in several processes, including cerebral cortex neuron differentiation; negative regulation of circadian rhythm; and regulation of axon extension. Acts upstream of or within several processes, including cellular response to glucose stimulus; positive regulation of G2/M transition of mitotic cell cycle; and response to methylglyoxal. Located in kinetochore and nucleus. Part of transcription repressor complex. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; paraxial mesenchyme; and retina. Human ortholog(s) of this gene implicated in chromosome 15q24 deletion syndrome. Orthologous to human SIN3A (SIN3 transcription regulator family member A).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
