The WEE1 (Phospho-Ser642) antibody detects the phosphorylated form of WEE1 kinase at serine 642. a key post-translational modification regulating its activity. WEE1 is a serine/threonine kinase critical in cell cycle control, particularly during the G2/M checkpoint. It phosphorylates and inhibits cyclin-dependent kinase 1 (CDK1/cyclin B), preventing premature entry into mitosis to ensure DNA repair. Phosphorylation at Ser642. located in the catalytic domain, is associated with WEE1's activation or stabilization, often mediated by upstream kinases like CDK1/2 during cell cycle progression or DNA damage responses. This modification may influence WEE1’s substrate specificity or interaction with regulatory partners.
Research using Phospho-Ser642-specific antibodies helps investigate WEE1’s role in maintaining genomic stability, cancer biology (e.g., tumor suppression vs. oncogenic roles), and cellular responses to replication stress or chemotherapeutic agents. Dysregulation of WEE1 phosphorylation is linked to checkpoint bypass, mitotic defects, and cancer progression. The antibody is widely employed in techniques like Western blotting, immunofluorescence, or flow cytometry to study cell cycle dynamics, DNA damage pathways, and therapeutic targeting of WEE1 in diseases such as solid tumors, where WEE1 inhibitors are under clinical evaluation.
