    basic FUNCTION
  • semaphorin 3C and 3F receptor
  • implicated in repulsive axon guidance and vascular endothelial growth factor
  • can function in the absence of NRP1 to mediate endothelial tube formation in hypoxia
  • involved in the organization and fasciculation of several cranial nerves and spinal nerves
  • function as receptors for both the semaphorins and vascular endothelial growth factor
  • can function in the absence of NRP1 to mediate endothelial tube formation in hypoxia
  • important role in cancer and angiogenesis
  • cell surface receptor involved in angiogenesis and axonal guidance, has recently been shown to be a critical mediator of tumor-associated lymphangiogenesis
  • NRP2 is a mediator of prorelaxant stimuli in SMCs, suggesting a novel function for NRP2 as a regulator of visceral smooth muscle (SM) contractility
  • NRP1 and NRP2 are receptors for guidance cues of the class 3 semaphorin (SEMA) family and are expressed in partially overlapping patterns in sympathetic neural crest (NC) cells and their progeny
  • role of NRP2 in the ipsilateral growth of midbrain dopaminergic axons
  • physiological role for NRP2 in bone homeostasis
  • SEMA3F and NRP2 are further regulators of human thymocyte migration in physiological and pathological conditions
  • NRP1 and NRP2 are transmembrane glycoproteins that are essential for Neural crest cells (NCCs) migration
  • NRP1, NRP2 play an essential role in coordinating NCC migration with fate specification
  • is a non-tyrosine kinase receptor frequently overexpressed in various malignancies
  • novel function of NRP2 as a regulator of endocytosis, which is enhanced in cancer cells and is often associated with increased metastatic potential and drug resistance
  • WDFY1 functioned downstream of NRP2 to promote endosome maturation, thereby influencing the endosomal trafficking of EGFR and the formation of autolysosomes responsible for the degradation of internalized cargo
  • regulation of WDFY1 transcription by NRP2 axis is a critical event in maintaining metastatic phenotype in cancer cells
  • SEMA3A, -3C, and -3F, likely with coreceptors NRP1, NRP2, and plexin-A1 and/or -A3, promote migration and possibly other activities of human DCs during innate and adaptive immune responses
  • new role for NRP2 in the positioning of neurons during adult hippocampal neurogenesis, acting via the GSK3B signaling pathway
  • NRP1 and NRP2 are co-receptors for heparin-binding growth factors and class 3 semaphorins

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • receptors for the semaphorin family of axon guidance molecules, and is critical for development of the nervous system
  • interactions between NRP2 and secreted semaphorins function to coordinate repulsive axon guidance during neurodevelopment (Giger 1998)
  • transmembrane receptor for the lymphangiogenic vascular endothelial growth factor C (VEGFC), playing an important role in lymphatic vessel sprouting
  • interaction between NRP2 and FLT4 mediates proper lymphatic vessel sprouting in response to VEGFC
  • motoneuronal SEMA3C regulates the shared SEMA3 neuropilin receptors NRP1 and NRP2 levels in opposite ways at the growth cone surface
  • GATA2 and LMO2 cooperatively regulate VEGFA-induced angiogenesis and lymphangiogenesis via NRP2
  • controls endothelial cell migration and tumor angiogenesis by altering NRP2 expression
  • in thyroid cells PAX8 directly binds the Neuropilin-2 promoter leading to its transcriptional repression
  • SEMA3F provides neuronal guidance cues via its ability to bind neuropilin 2 (NRP2) and Plexin A family molecules
  • NRP2 inhibits WDFY1 transcription by preventing the nuclear localization of a transcription factor, BPTF
  • SEMA3G induces cell collapse in an NRP2/PLXND1-dependent manner
  • SEMA3A binds its receptors neuropilin NRP1 or NRP2 to position these axons for correct GnRH neuron migration, with an additional role for the NRP co-receptor PLXNA1
  • NRCAM stabilizes binding between NRP2 and PLXNA3 necessary for SEMA3F-induced spine pruning
