Plexin-B1 activates RhoA and induces growth cone collapse and and cytoskeletal reorganization through Rho-specific guanine nucleotide exchange factors PDZ-RhoGEF (ARHGEF11) and leukemia-associated RhoGEF (LARG, ARHGEF12). Plexin-B1 directly interacts with PDZ-RhoGEF through its c-terminal PDZ domain binding motif. It has been suggested that Rnd1, which binds to the cytoplasmic part of plexin-B1, can promote the interaction between plexin-B1 and PDZ-RhoGEF. The PDZ domain of LARG is directly involved in the interaction with the c-terminal sequence of Plexin-B1.
