Functioni

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 (PubMed:10399920, PubMed:9126742). Functions as netrin receptor that negatively regulates vascular branching during angiogenesis. Mediates retraction of tip cell filopodia on endothelial growth cones in response to netrin (By similarity). It also acts as a dependence receptor required for apoptosis induction when not associated with netrin ligand (PubMed:11387206). Mediates apoptosis by activating DAPK1 (PubMed:18582460). In the absence of NTN1, activates DAPK1 by reducing its autoinhibitory phosphorylation at Ser-308 thereby increasing its catalytic activity (PubMed:15729359).By similarity1 Publication4 Publications

Mainly expressed in regions of differentiating neurons. Expressed in the developing sensory ganglia that flank the spinal cord from E12, peaking at E14. Expressed in the roof plate region of the spinal cord from E14.1 Publication

Interactioni

Subunit structurei

Interacts with the cytoplasmic part of DCC (PubMed:10399920). Interacts with GNAI2 via its cytoplasmic part (By similarity). Interacts (via death domain) with DAPK1 (via death domain) (PubMed:15729359, PubMed:18582460). Interacts (via extracellular domain) with FLRT3 (via extracellular domain); the interaction is direct. Interacts (via extracellular domain) with FLRT2 and FLRT3 (via extracellular domain), but has higher affinity for FLRT3. Identified in a complex with FLRT3 and ADGRL3; does not interact with ADGRL3 by itself (By similarity).By similarity3 Publications
