Summary: Enables transcription corepressor activity. Acts upstream of or within several processes, including entrainment of circadian clock; negative regulation of transcription, DNA-templated; and response to hydrogen peroxide. Located in nucleus. Part of transcription regulator complex. Is expressed in brain; eye; integument; and kidney. Human ortholog(s) of this gene implicated in advanced sleep phase syndrome. Orthologous to human CRY1 (cryptochrome circadian regulator 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
