HASPIN (Histone H3 Associated Protein Kinase): HASPIN is a kinase that phosphorylates histone H3, playing a crucial 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 lead to chromosomal abnormalities and is being investigated for its potential involvement in cancer development and as a target for cancer therapies.
