CSK (C-Src Tyrosine Kinase): CSK is a key regulatory enzyme that phosphorylates and thereby inhibits Src family tyrosine kinases, crucial components in signaling pathways for cell growth, differentiation, and survival. Dysregulation of CSK activity can lead to aberrant cellular signaling, contributing to the development of cancer and other diseases. Understanding CSK's regulatory mechanisms provides insights into the control of cell signaling and offers potential avenues for therapeutic intervention in diseases driven by tyrosine kinase dysregulation....
