简介
Chk1 is a serine/threonine protein kinase that critically coordinates checkpoint-mediated cell cycle arrest and DNA repair in response to DNA damage or unreplicated DNA. It negatively regulates unperturbed cell cycle progression and protects genome integrity by phosphorylating key targets such as CDC25A, CDC25B, CDC25C, RAD51, TP53, histone H3.1, RB1, SPRTN, TLK1 and FANCE. Chk1 Protein, Mouse (sf9, His-GST) is the recombinant mouse-derived Chk1 protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag.

Protein Description
CHK1 (Checkpoint Kinase 1) is a pivotal serine/threonine protein kinase that plays a crucial role in the cellular response to DNA damage and the regulation of the cell cycle. Its primary function is to maintain genomic stability by orchestrating the DNA damage response (DDR) pathways, particularly in the S and G2 phases of the cell cycle. Dysregulation of CHK1 has been implicated in various cancers, making it an attractive target for therapeutic interventions. Research into CHK1 recombinant proteins has gained momentum as they can be utilized to better understand its biochemical properties, signaling pathways, and interactions with other cellular proteins. Additionally, CHK1 inhibitors have emerged as promising cancer treatments, particularly in combination with other therapies such as chemotherapy and radiation, with the aim of enhancing the efficacy of these treatments by altering tumor cell responses. The production and characterization of CHK1 recombinant proteins enable scientists to dissect its functional mechanisms, investigate the structural basis for its interactions, and explore potential avenues for drug development. Given the critical role of CHK1 in cancer biology and therapeutic response, ongoing research seeks to elucidate its intricate network of regulation and establish a foundation for the application of CHK1-targeted therapies in clinical settings. This emerging field not only provides insights into cancer pathophysiology but also opens up new opportunities for innovative treatment strategies aimed at improving patient outcomes.
