HASPIN (Histone H3 Associated Protein Kinase): HASPIN is a kinase that phosphorylates histone H3, playing a key role in regulating chromosome condensation and segregation during mitosis. It is essential for maintaining genomic stability and ensuring proper cell division. Dysregulation of HASPIN activity can cause chromosomal abnormalities and is being studied for its potential involvement in cancer development and as a target for cancer therapies.
