Summary
Enables transcription corepressor activity. Acts upstream of or within inner cell mass cell proliferation; negative regulation of transcription, DNA-templated; and skeletal muscle cell differentiation. Located in nucleus. Part of COP9 signalosome. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Orthologous to human COPS2 (COP9 signalosome subunit 2). [provided by Alliance of Genome Resources, Apr 2022]

  2. Cops2, but not the whole COP9 signalosome, is essential for pluripotency maintenance in mouse embryonic stem cells. Down-regulation of Cops2 reduces expression of pluripotency genes, slows proliferation rate, arrests G2/M cell cycle, and compromises ESC embryoid differentiation. Cops2 binds to Nanog protein and prevents degradation. Cops2 functions as transcriptional corepressor to facilitate pluripotency maintenance.

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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (4) has multiple differences compared to variant 1.
