netrin receptor UNC5D (Unc-5 homolog D, Unc-5 homolog 4, UNC5D, UNC5H4, KIAA1777, UNQ6012/PRO34692)

Function

• receptor for netrin
• involved in axon guidance
• mediates axon repulsion of neuronal growth cones in developing nervous system
• association with DCC (cytoplasmic domain) may trigger signaling for axonal repulsion
• corticospinal tract axon guidance, independent of DCC
• apoptosis induction when NOT associated with netrin
• phosphorylated on different cytoplasmic Tyr
• proteolytic cleavage by caspases during apoptosis does NOT occur associated with netrin ligand.
• cleavage by caspases is required to induce apoptosis

Structure

• belongs to the unc-5 family
