Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Predicted to enable chemorepellent activity; neuropilin binding activity; and semaphorin receptor binding activity. Involved in several processes, including T-helper 1 cell differentiation; negative regulation of angiogenesis; and positive regulation of synapse assembly. Predicted to be active in plasma membrane. Is expressed in several structures, including blood vessel; central nervous system; primitive ventricle; retina; and ureteric trunk. Human ortholog(s) of this gene implicated in cone-rod dystrophy 10 and retinitis pigmentosa 35. Orthologous to human SEMA4A (semaphorin 4A). PHENOTYPE: Homozygotes for a knock-out allele show no obvious brain defects but exhibit impaired T cell priming and defective Th1 responses. Homozygotes for a gene trap allele show severe retinal degeneration with reduced retinal vessels, depigmentation and dysfunction of both rod and cone photoreceptors. [provided by MGI curators] |
