Function
UNC5B_MOUSE Receptor for netrin required for axon guidance. Mediates axon repulsion of neuronal growth cones in the developing nervous system upon ligand binding. Axon repulsion in growth cones may be caused by its association with DCC that may trigger signaling for repulsion. It also acts as a dependence receptor required for apoptosis induction when not associated with netrin ligand (By similarity). Mediates apoptosis by activating DAPK1. In the absence of NTN1, activates DAPK1 by reducing its autoinhibitory phosphorylation at Ser-308 thereby increasing its catalytic activity (By similarity).[1]

Publication Abstract from PubMed
UNC5Hs (UNC5H1-4) are netrin 1 receptors that are involved in axonal guidance and neuronal migration. They are dependence receptors that mediate apoptosis in the absence of netrin 1. UNC5H2-induced apoptosis depends on the interaction of the death domain at the C-terminus with the DAP-kinase death domain and caspase cleavage near the transmembrane region. Here, the crystal structure of the mouse UNC5H2 death domain has been determined at 2.1 A resolution. The domain adopts a six-helix bundle fold, which is similar to those of the other members of the death-domain superfamily. The UNC5H2 death domain is a dimer in the crystal and in solution. This homodimerized structure may represent the structure of the death domain when netrin 1 binds to the UNC5H2 receptor. Homodimerization of UNC5H2 may block the access of caspase to the cleavage site. In the death-domain dimer, residues in alpha3 and the 3(10)-helix preceding alpha3 and the residues in alpha4 make significant contacts, mainly by hydrophobic and van der Waals interactions.
