Recombinant Human Membrane-associated tyrosine- and threonine-specific cdc2-inhibitory kinase (PKMYT1)

Uniprot Id

Q99640

Target Species

Human

Target Name

PKMYT1

Target Full Name

Membrane-associated tyrosine- and threonine-specific cdc2-inhibitory kinase

Target Function

Acts as a negative regulator of entry into mitosis (G2 to M transition) by phosphorylation of the CDK1 kinase specifically when CDK1 is complexed to cyclins. Mediates phosphorylation of CDK1 predominantly on 'Thr-14'. Also involved in Golgi fragmentation. May be involved in phosphorylation of CDK1 on 'Tyr-15' to a lesser degree, however tyrosine kinase activity is unclear and may be indirect. May be a downstream target of Notch signaling pathway during eye development.

Target Subcellular Location

Endoplasmic reticulum membrane; Peripheral membrane protein. Golgi apparatus membrane; Peripheral membrane protein.

Target Protein Families

Protein kinase superfamily, Ser/Thr protein kinase family, WEE1 subfamily

Target Background

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.
