Mouse Neogenin Antibody

Neogenin (NEO) 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 (1). Mouse NEO is widely expressed in adult tissues and is expressed throughout the mid to late stages of gestation, in both neuronal and non-neuronal tissues. It is a member of the immunoglobulin (Ig) superfamily and is closely related to deleted in colorectal cancer (DCC). Mouse NEO cDNA encodes a 1493 amino acid residue (aa) precursor with a putative 36 aa signal peptide, a 1100 aa extracellular domain with six Ig-like C2 type domains and three fibronectin type III domains, a 21 aa transmembrane domain, and a 345 aa cytoplasmic domain. At least five isoforms are produced in mice by alternative splicing. Mouse NEO shares 96%, 93%, and 86% aa sequence identity with rat, human, and chicken NEO, respectively. It also has 46% and 29% sequence homology with mouse DCC and C. elegans UNC40, a homolog of 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 (2, 3). In mouse, at least five netrins (netrin‑1, ‑3, -4, G1, and G2) have been identified (3-5). Mouse netrin-1 and netrin-3 have been shown to be ligands for mouse NEO.
