Background
CHEK1(Serine/threonine-protein kinase Chk1) involved in cell cycle arrest when dna damage has occurred or when unligated dna is present. CHEK1 binds to and phosphorylates CDC25A, CDC25B and CDC25C. The phosphorylation of CDC25C creates a binding site for 14-3-3 protein which inhibits CDC25C. This prevents activation of the CDC2-Cyclin B complex and prevents mitotic entry. The CHEK1 phosphorylates CDC25C on serine216. Chk1 plays a primary role in the protection of cells from death induced by replication fork stress, whereas p21 mediates through its role in regulating entry into S phase. Chk1 deficiency resulted in a premature onset of mitosis because of abnormal activation of cyclin B-Cdc2 and led to the activation of caspases 3 and 9 triggered by cytoplasmic release of cytochrome c. It belongs to the Ser/Thr family of protein kinases and NIM1 subfamily.
