Mouse Anti-BDNF Recombinant Antibody (3D9C5) (CBMAB-0117CQ)

Brain Derived Neurotrophic Factor

This gene encodes a member of the nerve growth factor family of proteins. Human BDNF, which encodes a deduced 247 preproprotein that is proteolytically processed into a mature 119-amino acid protein. The mature BDNF protein shares 100% identity with mature porcine Bdnf and 52% identity with mature human NGF. Northern blot analysis detected BDNF transcripts of 1.6 and 4.0 kb in all brain regions examined. Expression of this gene is reduced in Alzheimer's, Parkinson's, and Huntington's disease patients. This gene may play a role in the regulation of the stress response and in the biology of mood disorders.

Important signaling molecule that activates signaling cascades downstream of NTRK2 (PubMed:11152678).
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.
BDNF precursor form: Important signaling molecule that activates signaling cascades downstream of NTRK2. Activates signaling cascades via the heterodimeric receptor formed by NGFR and SORCS2 (PubMed:24908487, PubMed:29909994).
Signaling via NGFR and SORCS2 plays a role in synaptic plasticity and long-term depression (LTD). Binding to NGFR and SORCS2 promotes neuronal apoptosis. Promotes neuronal growth cone collapse (By similarity).

Secreted
BDNF precursor form: Secreted. A proportion of BDNF is secreted as immature precursor (proBDNF).

Congenital central hypoventilation syndrome (CCHS): Rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia.

BDNF precursor form: N-glycosylated and glycosulfated, contrary to mature BDNF.
Mature BDNF is produced by proteolytic removal of the propeptide, catalyzed by a FURIN family member. In addition, the precursor form is proteolytically cleaved within the propeptide, but this is not an obligatory intermediate for the production of mature BDNF (PubMed:11152678). Can be converted into mature BDNF by plasmin (PLG) (PubMed:19467646).
