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 vital for maintaining genomic stability and ensuring accurate cell division. Dysregulation of HASPIN activity can lead to chromosomal abnormalities and is being explored for its potential role in cancer development as well as a target for cancer treatments.
