| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
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. |
