    Summary
    Predicted to enable ATP binding activity and protein serine/threonine kinase activity. Acts upstream of or within DNA damage response. Is expressed in eye; head; optic tectum; and proliferative region. Human ortholog(s) of this gene implicated in several diseases, including Li-Fraumeni syndrome 2; breast cancer (multiple); colorectal cancer; osteosarcoma; and prostate cancer. Orthologous to human CHEK2 (checkpoint kinase 2). [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.
