# Protein Tyrosine Kinase Research Tools: Advancements and Applications
## Introduction
Protein tyrosine kinases (PTKs) play a crucial role in cellular signaling pathways, regulating processes such as cell growth, differentiation, and apoptosis. As key players in various diseases, including cancer and autoimmune disorders, PTKs have become prime targets for drug development. This article explores the latest advancements in protein tyrosine kinase research tools and their applications in modern biomedical research.
