Structure of human Membrane-associated Tyrosine- and Threonine-specific cdc2-inhibitory kinase MYT1 (PKMYT1)

Function

[PMYT1_HUMAN] 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.^{[1] [2]}
