Summary: Enables protein kinase activity. Acts upstream of or within several processes, including cellular response to gamma radiation; signal transduction by p53 class mediator; and thymocyte apoptotic process. Predicted to be located in Golgi apparatus and PML body. Predicted to be active in cytoplasm and nucleus. Predicted to colocalize with chromosome, telomeric region. Is expressed in several structures, including central nervous system; genitourinary system; and liver. 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.
