# Protein Tyrosine Kinase Research Tool: A Comprehensive Guide for Scientists

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 cellular processes such as growth, differentiation, metabolism, and apoptosis. Given their fundamental importance in both normal physiology and disease states, PTKs have become prime targets for drug discovery and therapeutic intervention.
