    Summary
    Predicted to enable cyclin-dependent protein serine/threonine kinase activator activity; protein kinase binding activity; and protein serine/threonine kinase activity. Predicted to be involved in several processes, including negative regulation by host of viral genome replication; positive regulation of transcription elongation by RNA polymerase II; and transcription by RNA polymerase II. Predicted to act upstream of or within DNA damage response; in utero embryonic development; and negative regulation of stem cell differentiation. Predicted to be located in nucleoplasm. Predicted to be part of cyclin K-CDK12 complex; cyclin K-CDK13 complex; and cyclin/CDK positive transcription elongation factor complex. Predicted to be active in nucleus. Orthologous to human CCNK (cyclin K). [provided by Alliance of Genome Resources, Dec 2024]

    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.
