UNC5B (Unc-5 Netrin Receptor B) is a Protein Coding gene. Among its related pathways are Netrin-1 signaling and Netrin Signaling. UNC5B encodes a member of the netrin family of receptors. This particular protein mediates the repulsive effect of netrin-1 and is a vascular netrin receptor. This encoded protein is also in a group of proteins called dependence receptors (DpRs) which are involved in pro- and anti-apoptotic processes. Many DpRs are involved in embryogenesis and in cancer progression. Two alternatively spliced transcript variants have been described for UNC5B.
