Sema3E acts as a repellent on neurons expressing PlexinD1 alone, but the extracellular domain of Neuropilin-1 (co-expressed with PlexinD1) is sufficient to convert Sema3E/PlexinD1 repulsive signaling to attraction, defining a 'gating' function of neuropilins in semaphorin-plexin signaling during forebrain axon tract development. |

Full-length Sema3E is proteolytically processed by furin-dependent cleavage to generate a p61-Sema3E isoform; this truncated form is required and sufficient for pro-metastatic, pro-migratory, invasive-growth, and ERK1/2-activating activities in endothelial and pheochromocytoma cells, whereas full-length Sema3E acts as a repelling cue. |

Sema3E expressed by specific motor neuron pools signals through its high-affinity receptor Plexin D1 on proprioceptive sensory neurons as a repellent cue to establish monosynaptic sensory-motor circuit specificity; altering Sema3E-Plxnd1 expression in either sensory or motor neurons causes functional and anatomical rewiring of monosynaptic connections. |

Sema3E signals through Plexin D1 in cancer cells to promote invasion and metastasis via transactivation of the Plexin D1-associated ErbB2/Neu oncogenic kinase; knockdown of either Sema3E or Plexin D1 impairs metastatic potential, while overexpression increases invasiveness, transendothelial migration, and metastatic spreading in mice. |

Recombinant wild-type SEMA3E protects maturing GnRH neurons from apoptosis by triggering PLXND1-dependent activation of PI3K-mediated survival signaling; a Kallmann syndrome-associated point mutation in SEMA3E abrogates this neuroprotective activity; loss of either SEMA3E or PLXND1 in mice increases GnRH neuron apoptosis and reduces median eminence innervation. |

Sema3E directly inhibits Rap1 activation and LFA-1-dependent adhesion in thymocytes through the GTPase-activating protein (GAP) activity of Plexin D1; this suppresses immunological synapse (IS) formation and Ag-scanning migration of thymocytes, promoting their positioning in the thymic medulla. |

Sema3E/PlexinD1 signaling inhibits postischemic angiogenesis by: (1) suppressing DLL4 expression via inhibiting Rac1-induced JNK phosphorylation in brain microvascular endothelial cells; and (2) promoting F-actin disassembly and focal adhesion reduction by activating RhoJ through release of RhoGEF Tuba from direct binding to PlexinD1, causing endothelial filopodia retraction. |

Repulsive Sema3E-Plexin-D1 signaling induces expression of Mtss1 (metastasis suppressor 1) in striatonigral neurons as an autoregulatory feedback; Mtss1 localizes to the axonal side of neurites, promotes neurite outgrowth, and aids Plexin-D1 trafficking to the growth cone where it mediates collapse in response to Sema3E; Mtss1 KO mice exhibit fewer striatonigral projections and irregular axonal routes, phenocopying Plxnd1 and Sema3e KO mice. |
