Checkpoint kinase 1, commonly referred to as Chk1, is a serine/threonine-specific protein kinase that, in humans, is encoded by the CHEK1 gene. Chk1 coordinates the DNA damage response (DDR) and cell cycle checkpoint response. Activation of Chk1 results in the initiation of cell cycle checkpoints, cell cycle … See more In 1993, Beach and associates initially identified Chk1 as a serine/threonine kinase which regulates the G2/M phase transition in fission yeast. Constitutive expression of Chk1 in fission yeast was shown to induce … See more Human Chk1 is located on chromosome 11 on the cytogenic band 11q22-23. Chk1 has a N-terminal kinase domain, a linker region, a regulatory … See more DNA damage induces the activation of Chk1 which facilitates the initiation of the DNA damage response (DDR) and cell cycle checkpoints. The DNA damage response is a … See more During meiosis in human and mouse, CHEK1 protein kinase is important for integrating DNA damage repair with cell cycle arrest. CHEK1 is expressed in the testes and associates with meiotic synaptonemal complexes during the zygonema See more Checkpoint kinases (Chks) are protein kinases that are involved in cell cycle control. Two checkpoint kinase subtypes have been identified, Chk1 and Chk2. Chk1 is a central … See more Chk1 has a central role in coordinating the DNA damage response and therefore is an area of great interest in oncology and the development of cancer therapeutics.
