## Introduction to Protein Tyrosine Kinases

Protein tyrosine kinases (PTKs) are a crucial family 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 including growth, differentiation, and apoptosis.
