Description of target: Developmental neurite growth regulatory factor with a role as a negative regulator of axon-axon adhesion and growth, and as a facilitator of neurite branching. Regulates neurite fasciculation, branching and extension in the developing nervous system. Involved in down-regulation of growth, stabilization of wiring and restriction of plasticity in the adult CNS. Regulates the radial migration of cortical neurons via an RTN4R-LINGO1 containing receptor complex. Isoform 2 and isoform 3 inhibit BACE1 activity and amyloid precursor protein processing. Induces the formation and stabilization of endoplasmic reticulum (ER) tubules. Regulates membrane morphogenesis in the ER by promoting tubular ER production. Influences NE expansion, nuclear pore complex formation and proper localization of inner nuclear membrane proteins.;Species reactivity: Rat;Application: ;Assay info: Assay Methodology: Quantitative Sandwich ELISA;Sensitivity: 0.188 ng/mL
