Receptor for SEMA5A that plays a role in axon guidance, invasive growth and cell migration. Stimulates neurite outgrowth and mediates Ca(2+)/Mg(2+)-dependent cell aggregation. In glioma cells, SEMA5A stimulation of PLXNB3 results in the disassembly of F-actin stress fibers, disruption of focal adhesions and cellular collapse as well as inhibition of cell migration and invasion through ARHGDIA- mediated inactivation of RAC1. {ECO:0000269|PubMed:15218527, ECO:0000269|PubMed:20696765, ECO:0000269|PubMed:21706053}. This is the function of PLXNB3 (plexin B3, ENSG00000198753).
