Phospho-Wee1 (Ser123) Polyclonal Antibody, PE-Cy5.5 Conjugated

Product Specifications

Background

Acts as a negative regulator of entry into mitosis (G2 to M transition) by protecting the nucleus from cytoplasmically activated cyclin B1-complexed CDK1 before the onset of mitosis by mediating phosphorylation of CDK1 on 'Tyr-15'. Specifically phosphorylates and inactivates cyclin B1-complexed CDK1 reaching a maximum during G2 phase and a minimum as cells enter M phase. Phosphorylation of cyclin B1-CDK1 occurs exclusively on 'Tyr-15' and phosphorylation of monomeric CDK1 does not occur. Its activity increases during S and G2 phases and decreases at M phase when it is hyperphosphorylated. A correlated decrease in protein level occurs at M/G1 phase, probably due to its degradation.

Specificity

This phosphorylation site is homologous to Ser123 in Mouse, Rat, and Bovine. The peptide used to produce this antibody has high homology with a sequence occurring in MIER3, and may react with this protein in Mouse and Human when phosphorylated at the site of Ser10.
