Transfected cell immunofluorescence: COS cells expressing Myc-tagged human Haspin. Red = rabbit anti-Myc, Green = N128A/2, Blue = Hoechst nuclear stain.
Histone H3 Associated Protein Kinase is encoded by the gene HASPIN. HASPIN is a member of the protein kinase superfamily, Ser/Thr protein kinase family, and the Haspin subfamily. HASPIN is a serine/threonine - protein kinase that phosphorylates histone H3 at 'Thr-3' (H3T3ph) during mitosis. HASPIN may act through H3T3ph to both position and modulate activation of 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. HASPIN is expressed in the testis, thymus, bone marrow, prostate, intestine, lung, spleen, and lymph node. No diseases were found to be associated with HASPIN.
