Robo4 - roundabout guidance receptor 4

Enables signaling receptor activity. Acts upstream of or within negative regulation of cell migration. Located in external side of plasma membrane. Is expressed in several structures, including forebrain; genitourinary system; neural retina; submandibular gland; and vascular system. Human ortholog(s) of this gene implicated in aortic valve disease 3. Orthologous to human ROBO4 (roundabout guidance receptor 4). [provided by Alliance of Genome Resources, Apr 2022]
