Fms-related tyrosine kinase 3 ligand (FLT3LG)

Target
FLT3LG
Molecular classification
Cytokine, Endogenous peptide
01

Overview

Fms-related tyrosine kinase 3 ligand (FLT3LG) is a cytokine protein that acts as a growth factor, playing a crucial role in hematopoiesis, particularly in the proliferation and differentiation of blood cell progenitors. It stimulates the development, expansion, and mobilization of dendritic cells and increases immune cell numbers. FLT3LG exerts its effects by binding to its receptor, FMS-like tyrosine kinase 3 (FLT3/CD135), which leads to receptor activation and downstream signaling.
