Enables semaphorin receptor binding activity. Acts upstream of or within negative regulation of smooth muscle cell migration; positive regulation of smooth muscle cell migration; and ventricular system development. Located in collagen-containing extracellular matrix. Is expressed in several structures, including central nervous system; gut mesenchyme; retina; and spinal ganglion or nerve. Orthologous to human SEMA6D (semaphorin 6D). [provided by Alliance of Genome Resources, Apr 2022]
