Description
Product Characteristics:
PKMYT1 is a member of the serine/threonine protein kinase family. It preferentially phosphorylates and inactivates cell division cycle 2 protein (cdc2), and thus acts as a negative regulator of entry into mitosis (G2 to M transition). It mediates phosphorylation of cdc2 predominantly on 'Thr-14' and is also involved in Golgi fragmentation. It may be involved in phosphorylation of cdc2 on 'Tyr-15' to a lesser degree, however tyrosine kinase activity is unclear and may be indirect. It may be a downstream target of Notch signaling pathway during eye development. PKMYT1 is negatively regulated by hyperphosphorylation during mitosis.

Target Information: This gene encodes a member of the serine/threonine protein kinase family. The encoded protein is a membrane-associated kinase that negatively regulates the G2/M transition of the cell cycle by phosphorylating and inactivating cyclin-dependent kinase 1. The activity of the encoded protein is regulated by polo-like kinase 1. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
