Target
VEGFR-3
Molecular classification
Type IV Receptor Tyrosine Kinase (RTK), Vascular Endothelial Growth Factor (VEGF) receptor family, Receptor, Enzyme
01

Overview

Fms-like tyrosine kinase receptor 4 (FLT4), also known as VEGFR-3, is a receptor tyrosine kinase critical for lymphangiogenesis. It binds primarily to VEGF-C and VEGF-D and plays a key role in lymphatic vessel development and maintenance. It is implicated in diseases related to abnormal lymphangiogenesis, including lymphedema and tumor metastasis, making it a potential therapeutic target.
