Summary: Enables histone H3T11 kinase activity. Involved in negative regulation of gene expression, epigenetic. Acts upstream of or within several processes, including DNA damage checkpoint signaling; G2/M transition of mitotic cell cycle; and inner cell mass cell proliferation. Located in chromatin; nucleus; and replication fork. Is expressed in several structures, including adrenal medulla; brain; early conceptus; gonad; and gut. Human ortholog(s) of this gene implicated in pancreatic cancer. Orthologous to human CHEK1 (checkpoint kinase 1). [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.
