Summary: Enables cyclin binding activity; cyclin-dependent protein serine/threonine kinase activity; and magnesium ion binding activity. Involved in peptidyl-serine phosphorylation and positive regulation of cell population proliferation. Acts upstream of or within several processes, including G1/S transition of mitotic cell cycle; potassium ion transport; and regulation of nucleobase-containing compound metabolic process. Located in chromosome and nucleus. Part of cyclin-dependent protein kinase holoenzyme complex and transcription regulator complex. Is expressed in several structures, including brain; branchial arch; ear; integumental system; and limb. Human ortholog(s) of this gene implicated in prostate cancer and renal cell carcinoma. Orthologous to human CDK2 (cyclin dependent kinase 2). [provided by Alliance of Genome Resources, Jun 2025]
Expression: Broad expression in limb E14.5 (RPKM 35.9), thymus adult (RPKM 24.5) and 25 other tissues See more

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.
