Recombinant Human Neogenin Fc Chimera Protein, CF Summary
Accession # Q92859-1
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Neogenin is a type I transmembrane protein belonging to the Ig superfamily. It is composed of an extracellular segment containing four Ig-like C2 type domains and six Fibronectin type III domains (1). Neogenin has a molecular weight of approximately 190 kDa, and the extracellular domain of the human protein shares 91% and 93% amino acid sequence identity with the mouse and rat orthologues, respectively (1). Four different isoforms are produced from alternative splicing of human NEO1. Neogenin is widely expressed in adult human tissues with the highest levels being observed in skeletal muscle and pancreas (1). It is also ubiquitously expressed in both neuronal and non-neuronal tissues of the developing mouse embryo (2). Neogenin is a multifunctional cell surface receptor that binds to members of the Netrin, Repulsive Guidance Molecule (RGM) and Bone Morphogenetic Protein (BMP) families (3-5). It has also been shown to interact with members of the UNC5 family and in certain instances, associate with CDO as a co-receptor (6-8). Neogenin appears to be involved in the regulation of multiple developmental processes including development of the central nervous system (CNS), myogenesis, angiogenesis, and formation of mammary glands (4, 5, 7-9). During CNS development, Neogenin regulates neural tube closure, neuronal differentiation, and cell survival (4, 5, 7). It also mediates Netrin-1 dependent attraction and RGM-A dependent repulsion of growing axons (4, 5, 7, 10). Additionally, Neogenin binding to RGM and Netrin proteins regulates cell-cell adhesion, cell migration, tissue organization, and adult neurogenesis (4, 7, 11). Neogenin is thought to be involved in tumorigenesis and cancer cell invasiveness in brain and gastric cancers (12-14).
