Function
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.
Important signaling molecule that activates signaling cascades downstream of NTRK2 (By similarity).
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

Interaction
Subunit
Monomers and homodimers (By similarity).
Binds to NTRK2/TRKB. Can form heterodimers with other neurotrophin family members, such as NTF3 and NTF4 (in vitro), but the physiological relevance of this is not clear (By similarity).
BDNF precursor form: interacts with the heterodimer formed by NGFR and SORCS2. Mature BDNF has much lower affinity for the heterodimer formed by NGFR and SORCS2
