PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • serine/Threonine protein kinases, catalytic domain
  • one response regulatory domain
  • a very long T-loop (>500 AAs) that separates the kinase subdomains VII and VIII, a particular feature exclusive to Gwl kinases
  • HOMOLOGY
    interspecies ortholog to murine Mastl
    ortholog to ortholog of drosophila Greatwall protein kinase
    Homologene
    FAMILY
  • AGC family of serine/threonine kinases that phosphorylates substrates on S/T residues encircled by basic amino acids
  • CATEGORY receptor membrane serine/threonine kinase

    text
  • localizes to the nucleus in interphase and re-localizes in part to centrosomes in mitosis, when it is active
  • basic FUNCTION
  • involved in the activation of a meiotic genes activation pathway
  • promotes mitotic entry and maintenance in human cells by inhibiting protein phosphatase 2A (PP2A)
  • crucial for mediating this regulation in somatic human cells
  • mediates mitotic entry and maintains the mitotic state by inhibiting PP2A, and thus maintains the correct equilibrium between cyclin B-Cdc2 and PP2A
  • essential kinase for correct chromosome condensation and mitotic progression
  • enhances cyclin B1-Cdk1-dependent mitotic phosphorylation events, directing mitotic entry, anaphase and cytokinesis
  • phosphorylating in mitosis ENSA, converting ENSA into a potent and specific inhibitor of PPP2R2B/PPP2R2D
  • is required to maintain mitosis through PPP2R2B inhibition
  • CELLULAR PROCESS
