It is highly conserved in evolution, with homologous proteins present from fission yeast to humans. As a core effector molecule in the DNA damage response pathway, Chk1 is a direct substrate of the upstream sensor kinase ATR and is activated by ATR phosphorylation upon DNA replication stress or damage, thereby transmitting checkpoint signals by phosphorylating downstream target proteins such as the CDC25 phosphatase family. The primary function of Chk1 is to exert regulatory control during the S phase and G2\/M phase of the cell cycle, delaying mitotic entry by inhibiting CDK activity to provide a time window for DNA repair, thereby maintaining genomic stability. In addition, Chk1 participates in regulating centrosome and spindle checkpoints, inhibiting the activation of DNA replication origins, and suppressing the transcription of cell cycle proteins such as cyclin B and CDK1. In malignant tumors, Chk1 is often abnormally overexpressed, enhancing the DNA repair capacity of tumor cells and inducing resistance to chemotherapy and radiotherapy, making it an important molecular target for cancer therapy. Several Chk1 inhibitors have entered clinical trials, among which Prexasertib has been granted Fast Track designation by the FDA for the treatment of patients with platinum-resistant ovarian cancer and endometrial cancer.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Starter","offers":[{"title":"25μl","offer_id":67246578696267,"sku":"S0B60694-25μl","price":100.0,"currency_code":"USD","in_stock":true},{"title":"100μl","offer_id":67246578729035,"sku":"S0B60694-100μl","price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/03d31c269534417bae5baad90e348909.jpg?v=1792054906","url":"https:\/\/www.antbioinc.com\/products\/chk1-recombinant-mouse-mab-s-6263-s0b60694","provider":"AntBio","version":"1.0","type":"link"}
