Checkpoint Kinase 1 MeSH Descriptor Data 2026


MeSH Heading
Checkpoint Kinase 1
Tree Number(s)
D08.811.913.696.620.682.700.143
D12.776.476.563.143
Unique ID

RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D000071877
Scope Note
A serine/threonine-specific protein kinase which is encoded by the CHEK1 gene in humans. Checkpoint kinase 1 (also known as Chk1) coordinates DNA damage response and cell cycle checkpoint response. Under these conditions, activation of Chk1 results in the initiation of cell cycle checkpoints, cell cycle arrest, DNA repair and cell death, to prevent damaged cells from progressing through the cell cycle.
