General annotation (Comments)

Function

Oocyte-specific protein tyrosine kinase that phosphorylates and inhibits cdk1 and acts as a regulator of meiosis. Required to maintain meiotic arrest in oocytes by phosphorylating cdk1 at 'Tyr-15', leading to inhibit cdk1 activity and prevent meiotic reentry By similarity.

Catalytic activity

ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.

Subcellular location

Nucleus By similarity.

Sequence similarities

Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. WEE1 subfamily.

Contains 1 protein kinase domain.
