Protein

Wee1-like protein kinase 1-A

Gene

wee1-a

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Acts as a zygotic 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. Involved in convergent extension of the paraxial mesoderm during neurulation by inhibiting the cell cycle.2 Publications
