Chk1 is a protein-serine/threonine kinase required for checkpoint-mediated cell cycle arrest. It also subsequently activates DNA repair (i.e. homologous recombination) by phosphorylating RAD51 or FANCE in response to the presence of damage or unreplicated DNA. It regulates cell cycle progression via several mechanisms: 1) phosphorylation of certain proteins such as CDC25A, CDC25B and CDC25C, promoting their degradation; 2) phosphorylation and activation of p53; 3) phosphorylation and inactivation of TLK1, which consequently prevents TLK1-dependent phosphorylation of chromatin assembly factor ASF1A; 4) phosphorylation of histones and regulating transcription of genes involved in cell-cycle progression regulation; 5) phosphorylation of RB1 to promote its interaction with E2F transcription factors and subsequent cell cycle arrest
