    text
  • type I transmembrane protein (TM1)
  • localized along with the SSTR3 receptor to the primary cilia of the granule cells of the murine dentate gyrus, a center of adult neurogenesis
  • NGFR and NTRK1 are localized in the mitochondrial compartment of undifferentiated human podocytes and in all tissues analyzed including rat central nervous system
  • basic FUNCTION
  • important role in the development and function of sensory neurons
  • mediates neurotrophin-dependent apoptosis
  • involved in light-mediated photoreceptor apoptosis in vivo
  • is the signal transducing element for Myelin-associated glycoprotein
  • initiates intracellular signaling leading either to cell survival or to apoptosis
  • an essential role for p75(NTR)-related signalling in early embryonic morphogenesis
  • role in activity-dependent synaptic plasticity
  • receptor tyrosine kinase, class VI, regulating the myelination process in peripheral nervous system
  • a negative growth regulator within the context of myelin inhibition 5
  • may play a positive role in nerve regeneration
  • involved in the control of neuronal survival versus death and axonal regeneration and growth cone collapse
  • regulator of liver repair
  • binds pro and mature neurotrophins and affects the growth, differentiation and death of the nervous system
  • maintains the specificity of neural connectivity
  • regulator of glucose uptake and insulin resistance
  • unanticipated function of NGFR as a unique regulator of glucose metabolism and insulin sensitivity
  • transcriptional activation of NGFR is under circadian regulation in the nervous system and peripheral tissues, and plays an important role in the maintenance of clock and metabolic gene oscillation
  • influences the proliferation, survival, and differentiation of neuronal precursors and its expression is induced in injured brain, where it regulates cell survival
  • can modulate cell-fate decisions through its highly ramified signaling pathways
  • CELLULAR PROCESS cell life, cell death/apoptosis

  • brain-expressed X-linked 1, Bex1
  • par-3 partitioning defective 3 homolog (C. elegans), PARD3
  • MAGED1 (NGFR adaptor protein, required for developmental apoptosis)
  • SALL2 (SALL2 is a novel NGFR-interacting protein that links NGF signalling to cell cycle progression and neurite outgrowth)
  • serves as a receptor for the pro-forms of theneurotrophins
  • NPHS1 and NGFR share a partial overlapping expression pattern in the epicardium and subepicardial coronary vessels
  • interactions of RTN4R with its co-receptors LINGO1, NGFR and the myelin inhibitor RTN4 is facilitated by gangliosides
  • is required for the signal transduction of PILRB, which interacted with NGFR upon ligand binding
  • on oligodendroglial cells, LINGO1 interacts with NGFR to constitutively inhibit multiple aspects of oligodendrocyte differentiation
  • RAB5A and RAB31 directly interact with NGFR primarily via helix 4 of the NGFR death domain
  • NTRK1 and NGFR collaborate with each other at the plasma membrane to bind NGF
  • NGFRAP1 interacts with the death domain of NGFR and mediates apoptosis in neural cells in response to nerve growth factor
  • NGFR and NTRK1 interact to enhance neurotrophic signaling
  • NGFR associated predominantly with natively expressed LINGO1 containing immature N-glycans, characteristic of protein that has not completed trans-Golgi-mediated processing

    ANIMAL & CELL MODELS
  • mice with NGF receptor p75 mutation are viable and fertile display markedly decreased sensory innervation, loss of heat sensitivity associated with ulcers in the distal extremities
  • light-induced photoreceptor apoptosis in p75NTR knockout mice is significantly reduced
  • impairment of hippocampal long-term potentiation in p75NTR-deficient mouse
  • mice depleted for p75NTR exacerbate liver pathology and inhibited hepatocyte proliferation in vivo
