Roundabout homolog 4 (ROBO4)

Target
ROBO4
Molecular classification
Receptor, Single-pass transmembrane protein
01

Overview

Roundabout homolog 4 (ROBO4) is an endothelial-specific receptor that plays a key role in vascular biology. It promotes new blood vessel formation, guides proper organization of blood vessels, and is essential for endothelial cell migration and proliferation. ROBO4 interacts with ligands such as SLIT2 and is involved in maintaining vascular integrity. Its expression can be altered in pathological conditions like inflammation or cancer. Overexpression has been associated with glioma progression.
