# Protein Tyrosine Kinase Research Tools: Advances and Applications
Introduction to Protein Tyrosine Kinases
Protein tyrosine kinases (PTKs) are a crucial class of enzymes that play pivotal roles in cellular signaling pathways. These enzymes catalyze the transfer of phosphate groups from ATP to tyrosine residues on target proteins, thereby regulating various biological processes including cell growth, differentiation, and apoptosis. Given their importance in both normal physiology and disease states, PTKs have become prime targets for drug development and biomedical research.
