Chicken Netrin-2 Alexa Fluor™ Plus 594-conjugated Antibody

Netrins are laminin-like axon guidance molecules that are conserved among C. elegans, Drosophila, and vertebrates. The chicken Netrin-2 cDNA encodes a precursor protein that has structural similarity to the N-terminus of B2 or the gamma-chain of laminin. The mature Netrin-2 protein has 581 amino acid (aa) which contains a 245 aa domain VI, a 169 aa domain V with three cysteine/glycine rich EGF repeats and a unique 152 aa domain C that enriches in basic aa residues and contains an RGD motif. Chicken Netrin-2 shares 72% aa identity with chicken Netrin-1, 51% aa identity with C. elegans UNC-6 protein and 57% aa identity with human NTN2L (Netrin‑2‑like). Although only two chicken netrins are known, more mammalian netrins are known. Netrin-2 is expressed in the chick brain and spinal cord from E6 through to the adult. In addition, expression of Netrin‑2 was observed at various stages in several mesodermally and endodermally derived tissues, including lung, gut, ovary, testes and spleen. Netrins act to both attract and repel the growing axons of a broad range of neuronal cell types during development. These actions are mediated by specific receptor complexes containing either the DCC (colorectal carcinoma) or neogenin, in the case of attractant, or UNC-5-related proteins, in the case of repellent.
