Human/Mouse/Rat Netrin-1 Alexa Fluor™ Plus 488-conjugated Antibody

Netrin-1 (from Sanskrit netr meaning "to guide"; also known as Epididymis tissue protein Li 131P) is a 66-76 kDa secreted member of the laminin superfamily of molecules. It is expressed by multiple cell types, including embryonic neural tube ventral midline cells plus postnatal renal tubule epithelium and oligodendroglia. Netrin-1 has multiple receptors, including beta4-integrins, DCC, DSCAM and UNC5A-thru-D. Its effects are context specific. For example, on neurons, binding to either DCC or DSCAM alone promotes chemoattraction, while a DCC:UNC5 complex promotes chemorepulsion. In addition, the ligation of UNC5B on leukocytes suppresses cytokine production, while the binding of netrin to DCC expressed on select cell types inhibits apoptosis. Mature human netrin-1 is 580 amino acids (aa) in length (aa 25-604). It contains an N-terminal laminin domain (aa 47-284), three EGF-like domains (aa 285-453) and a C-terminal cell-interaction netrin-like domain (aa 472-601). Over aa 22-604, human netrin-1 shares 99% aa sequence identity with mouse netrin-1.
