Unc5 netrin receptors mediate repellent responses to netrin. Four Unc5 members have been found in humans: Unc5A, B, C and D. Different studies have suggested that long-range repulsion to netrin requires the cooperation of Unc5 and DCC, but that Unc5 without DCC is sufficient for short-range repulsion. The binding of netrin to Unc5 triggers the phosphorylation of Unc5 in its ZU-5 domain. Several proteins have been proposed to interact with Unc5 family members in mediating a repellent response, including tyrosine phosphatase Shp2, the F-actin anti-capping protein Mena, and ankyrin
