Background: UNC5H2/UNC5B

Netrin Receptor UNC5B is one of four related receptors that comprise the UNC5 family and serve as receptors for the axon guidance molecule Netrin-1. UNC5B is a type I transmembrane protein that contains two Ig-like and two thrombospondin domains in its extracellular domain (ECD), and a ZU5 domain, a DCC-binding domain, and a death domain in its intracellular region (1, 2). It is widely expressed in various embryonic and adult tissues including neural, hematopoietic, and immune tissues (1, 3, 4). Human UNC5B has a predicted molecular weight of approximately 104 kDa. Its ECD shares approximately 92% amino acid sequence identity within shared regions in the mouse and rat orthologs, which are termed UNC5H2. UNC5B regulates axon guidance by facilitating Netrin-1-mediated axon repulsion of neuronal growth cones (1). It complexes with the attractive Netrin receptor DCC and switches its response to Netrin-1 from attraction to repulsion (5). UNC5B can also induce growth cone collapse via its associations with the RGM-A receptor Neogenin and the soluble ECD of FLRT3 (2, 6). Outside of the nervous system, UNC5B facilitates Netrin-1-mediated inhibition of capillary branching and leukocyte migration, as well as Netrin-1-mediated promotion of osteoclast differentiation (7-10). UNC5B also functions as a dependence receptor. In the absence of Netrin-1, UNC5B mediates p53-dependent apoptosis via activation of DAPK (11, 12). UNC5B is believed to play a role in tumorgenesis. It has been shown to inhibit tumor cell growth and invasion, and its expression appears to be down-regulated in multiple cancers including colorectal, breast, ovary, uterus, stomach, lung, and kidney (13, 14). Additionally, UNC5B is thought to play a critical role in the development of atherosclerosis and the survival of renal tubular epithelial cells during acute kidney injury (15, 16).
