Summary: 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.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
