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. Given their importance in both normal physiology and disease, PTKs have become a major focus of biomedical research. To study these enzymes effectively, researchers rely on a variety of specialized tools and techniques. This article explores the latest advancements in PTK research tools and their applications in understanding kinase biology and developing therapeutic interventions.

Key Research Tools for Studying Protein Tyrosine Kinases
