The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.2 µg/ml. Detects a band of approximately 90 kDa (predicted molecular weight: 88 kDa).


  • FunctionRequired for normal alignment of chromosomes at metaphase. Phosphorylates histone H3 'Thr-3' during mitosis.
  • Tissue specificityStrongly expressed in testis. Also present in thymus and bone marrow and low levels observed in prostate, intestine, lung, spleen and lymph node. Expressed in fetal skin, liver, kidney and small intestine and also in proliferating but not non-proliferating cell lines.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Ser/Thr protein kinase family. Haspin subfamily.
    Contains 1 protein kinase domain.
  • Post-translational
    Autophosphorylated on both serine and threonine residues (By similarity). Phosphorylated during mitosis. Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localizationNucleus.

    Performed under reducing conditions.

    Predicted band size : 88 kDa
    Observed band size : 90 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 23 kDa. We are unsure as to the identity of these extra bands.
