Attractive and repulsive receptors regulate cell motility and attachment in axon guidance, vascular growth, immune cell regulation and tumor progression. There is strong evidence that development of the nervous and vascular systems is controlled by common cues.
Semaphorins, Ephrins, SLITs and Netrins are the four major guidance factors. Their cognate receptors are Plexins and Neuropilins, Ephs, ROBOs, UNC5 and DCC.
SLITs belong to repulsive cues. Intracellular molecular mechanisms leading to repulsive responses involve cytoskeletal reorganization.
Small GTPases play important role in this signaling .
Another signaling pathway that guidance signals to the regulation of cytoskeletal dynamics is the c-Abl protein kinase pathway. This pathway mediates signals downstream of the multiple ROBO receptors .
