Target intelligence / Profile preview

Tyrosine-protein kinase JAK2 (JAK2)

Target
JAK2
Molecular classification
Protein kinase superfamily, Janus kinase family, Enzyme, Non-receptor tyrosine kinase
01

Overview

Tyrosine-protein kinase JAK2 is a non-receptor tyrosine kinase that plays a crucial role in cell growth, development, differentiation, and histone modifications. It is a central component of the JAK/STAT signaling pathway, mediating signals from cytokine receptors to regulate gene expression. Dysregulation of JAK2 is implicated in various myeloproliferative disorders.

Other names
Janus kinase 2JTK10THCYT3JAK-2
02

Mechanism of action

JAK2 inhibitors block the kinase activity of JAK2, thereby inhibiting the JAK/STAT signaling pathway.
