Function
UNC5B_RAT 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. 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).

Publication Abstract from PubMed
The cytoplasmic domains of UNC5 are responsible for its netrin-mediated signaling events in axonal migrations, blood vessel patterning, and apoptosis, although the molecular mechanisms governing these processes are unknown. To provide a foundation for the elucidation of the UNC5-mediated signaling mechanism, we determined the crystal structure of the cytoplasmic portion of UNC5b. We found that it contains three distinctly folded domains, namely ZU5, UPA, and death domain (DD). These three domains form a structural supramodule, with ZU5 binding to both UPA and DD, thereby locking the ZU5-UPA-DD supramodule in a closed conformation and suppressing its biological activities. Release of the closed conformation of the ZU5-UPA-DD supramodule leads to the activation of the receptor in the promotion of apoptosis and blood vessel patterning. Finally, we provide evidence showing that the supramodular nature of UNC5 ZU5-UPA-DD is likely to be shared by the ankyrin and PIDD families of scaffold proteins.
