Netrin receptor

Function

Netrin receptors are cell surface proteins which bind netrins. Netrins direct cell and axon migration during development.

Netrin attraction is mediated through DCC (Deleted in Colorectal Cancer) receptors while netrin repulsion is mediated through the UNC-5 receptor^[1], ^[2] .
UNC-5B receptor or UNC-5H2 is a repulsive netrin recptor in endothelial cells controlling morphogenesis of the vascular system^[3].
UNC-5D receptor may mediate the effect of netrin-4 on cortical cell survival^[4].

Disease

DCC gene is deleted in most colorectal cancer patients as well as in other cancers^[5].

Structural highlights

Netrin DCC receptor extracellular domain contains 4 Ig repeats followed by 6 type III fibronectin repeats. Netrin UNC-5 receptor extracellular domain contains 2 Ig repeats followed by 2 type I thrombospondin repeats.
