Neogenin 1/NEO1 [MD160]

Neogenin (NEO1) is a type I transmembrane protein that is crucial for axonal guidance and neuronal migration. It is also involved in regulating differentiation programs in many embryonic and adult tissues. It is a member of the immunoglobulin (Ig) superfamily and is closely related to deleted in colorectal cancer (DCC). NEO and DCC, together with the UNC5 family of type I transmembrane proteins, are receptors for the netrin/UNC6 family of laminin-related bifunctional guidance molecules that both attract some axons and repel others. In mouse, at least five netrins (netrin‑1, ‑3, -4, G1, and G2) have been identified. Mouse netrin-1 and netrin-3 have been shown to be ligands for mouse NEO. Neogenin protein localizes to nuclear bodies and is thought to associate with chromatin and heterochromatin-associated factors. The protein is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains – a RING, a B-box type 1 and a B-box type 2 – and a coiled-coil region. Two alternatively spliced transcript variants encoding different isoforms have been described for this gene.
