Serine/threonine-protein kinase haspin

Gene

Gsg2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Serine/threonine-protein kinase that phosphorylates histone H3 at 'Thr-3' (H3T3ph) during mitosis. This positions and activates AURKB and other components of the chromosomal passenger complex (CPC) at centromeres to ensure proper chromatid cohesion, metaphase alignment and normal progression through the cell cycle.2 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Mg2+1 Publication

Enzyme regulationi

Constitutive activity that does not require phosphorylation. Specifically inhibited by 3-(1H-indazol-5-yl)-N-propylimidazo[1,2-b]pyridazin-6-amine (CHR-6494) (By similarity).By similarity

Post-translational modificationi

Autophosphorylated on both serine and threonine residues (By similarity). Strongly phosphorylated during mitosis but this does not appear to significantly affect its intrinsic kinase activity. Phosphorylation by AURKB is required for full activity toward histone H3 at 'Ser-3' in mitosis (By similarity).By similarity
