    Summary
    The protein encoded by this gene contains a kinase domain most closely related to the cyclin-dependent protein kinases. The encoded kinase may activate cyclin-dependent kinase 2 and is involved in cell growth. Alternatively spliced transcript variants encoding distinct isoforms have been reported.

    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: REVIEWED

      Description
      Transcript Variant: This variant (3) uses an alternate in-frame splice site in the 5' coding region and contains an alternate, in-frame exon in the middle portion of the coding region, compared to variant 1. This results in a longer protein (isoform 3), compared to isoform 1.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (5) uses an alternate in-frame splice site in the 5' coding region, and lacks an exon in the 3' coding region, which results in a frameshift compared to variant 1. This results in a shorter protein (isoform 5, also known as cardiac CCRK), compared to isoform 1.
