Given this fact, we propose that all three of these microcephaly disorders arise through defective regulation of Chk1. This defect in Chk1 function leads to increased cellular lethality in neural lineages and severely decreased brain and head size.

WebThe protein kinase Chk1 is required for cell cycle arrest in response to DNA damage. We have found that the 14-3-3 proteins Rad24 and Rad25 physically interact with Chk1 in fission yeast. ... that in fission yeast the interaction between the 14-3-3 proteins and Cdc25 does not require Chk1 function and is unaffected by DNA damage, in sharp ... 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. Initially Chk1 was thought to function as a tumor suppressor due to the regulatory role it serves amongst cells with DNA damage. However, there has … See more 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 … 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 … 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.
