  • Function

    May be involved in the regulation of cell-cell interactions or in synatogenesis during the maturation of the nervous system.
    NERP peptides are involved in the control of body fluid homeostasis by regulating vasopressin release.
  • Tissue specificity

    Central and peripheral nervous systems, synthesized exclusively in neuronal and neuroendocrine cells.
  • Post-translational

    Multiple peptides are derived from VGF, with activities in synaptic plasticity, antidepression, penile erection, autonomic activation, and increases in energy expenditure.
  • Cellular localization

    Secreted. Cytoplasmic vesicle > secretory vesicle. Stored in secretory vesicles and then secreted, NERP peptides colocalize with vasopressin in the storage granules of hypothalamus.

  • Immunohistochemical analysis of VGF in paraffin embedded human lung carcinoma tissue using ab74140, at a 1/50 dilution, in the presence (right panel) or absence (left panel) of immunising peptide.
  • ICC/IF image of ab74140 stained PC12 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab74140, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h.Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
