    motifs/domains
  • a tyrosine-serine
  • threonine dual specificity tyrosine kinase catalytic domain
  • C-terminal domain required for recruitment of CDK1, and this domain potentially lies in the cytoplasm because it can interact with and is phosphorylated by CDC
  • HOMOLOGY
    interspecies ortholog to Myt1Xe Xenopus laevis
    Homologene
    FAMILY
  • protein kinase superfamily
  • Ser/Thr protein kinase family
  • WEE1 subfamily

    basic FUNCTION
  • inhibitory kinase, negative regulator of the G2/M transition
  • its catalytic activity was not essential for the cell cycle delay observed with human cells
  • can negatively regulate CDK1/CCNB1 and inhibit G(2)/M progression by two means, both of which require the C-terminal domain (first, can bind and sequester CDK1/CCNB1 in the cytoplasm preventing entry into the nucleus, and, second, it can phosphorylate associated CDK1/CCNB1 at Thr14 and Tyr15 thus inhibiting its catalytic activity)
  • dual-specificity kinase that contributes to the regulation of the cell cycle by adding inhibitory phosphates to the cyclin-dependent kinases (Cdk/cyclins)
  • may be playing a key role in the G2 arrest of oocytes
  • inhibitory kinase for CDK1, the master engine of mitosis, and has been thought to function, together with WEE1, as a negative regulator of mitotic entry
  • essential role for Golgi and ER assembly during mitotic exit
  • CELLULAR PROCESS cell cycle
