  • Function
    During development, promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems. Participates in axonal growth, pathfinding and in the modulation of dendritic growth and morphology. Major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability.
  • Tissue specificity
    Brain. Highly expressed in hippocampus, amygdala, cerebral cortex and cerebellum. Also expressed in heart, lung, skeletal muscle, testis, prostate and placenta.
  • Involvement in disease
    Bulimia nervosa 2
    Congenital central hypoventilation syndrome
  • Sequence similarities
    Belongs to the NGF-beta family.
  • Post-translational
    The propeptide is N-glycosylated and glycosulfated.
    Converted into mature BDNF by plasmin (PLG).

    Performed under reducing conditions.

    Predicted band size: 15 kDa
    Additional bands at: 15 kDa (possible mature (processed) protein), 28 kDa (possible multimer), 35 kDa, 45 kDa (possible immature (unprocessed)). We are unsure as to the identity of these extra bands.

    This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with unpurified ab108319 (1/1000) overnight at 4°C. Ab8245 (mouse anti-GAPDH; 0.05 ug/mL) was included as a loading control. Antibody binding was detected using goat anti-rabbit IgG IR-680 (green) and goat anti-mouse IgG IR800 (red) at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx
