Chek1 - checkpoint kinase 1

Enables protein kinase activity. Involved in several processes, including DNA damage induced protein phosphorylation; cellular response to caffeine; and negative regulation of G2/M transition of mitotic cell cycle. Predicted to be located in several cellular components, including centrosome; chromosome; and nucleoplasm. Predicted to be part of protein-containing complex. Predicted to be active in nucleus. Predicted to colocalize with chromosome, telomeric region. Human ortholog(s) of this gene implicated in pancreatic cancer. Orthologous to human CHEK1 (checkpoint kinase 1).
