Rep. 6:31173-31173(2016). CC -!- FUNCTION: During development, promotes the survival and differentiation CC of selected neuronal populations of the peripheral and central nervous CC systems. Participates in axonal growth, pathfinding and in the CC modulation of dendritic growth and morphology. Major regulator of CC synaptic transmission and plasticity at adult synapses in many regions CC of the CNS. {ECO:0000256|RuleBase:RU364086}. CC -!- FUNCTION: Important signaling molecule that activates signaling CC cascades downstream of NTRK2 (By similarity). During development, CC promotes the survival and differentiation of selected neuronal CC populations of the peripheral and central nervous systems. Participates CC in axonal growth, pathfinding and in the modulation of dendritic growth CC and morphology. Major regulator of synaptic transmission and plasticity CC at adult synapses in many regions of the CNS. The versatility of BDNF CC is emphasized by its contribution to a range of adaptive neuronal CC responses including long-term potentiation (LTP), long-term depression CC (LTD), certain forms of short-term synaptic plasticity, as well as CC homeostatic regulation of intrinsic neuronal excitability. CC {ECO:0000256|ARBA:ARBA00025383}. CC -!- SUBUNIT: Monomers and homodimers (By similarity). Binds to NTRK2/TRKB. CC Can form heterodimers with other neurotrophin family members, such as CC NTF3 and NTF4 (in vitro), but the physiological relevance of this is CC not clear (By similarity). BDNF precursor form: interacts with the CC heterodimer formed by NGFR and SORCS2. Mature BDNF has much lower CC affinity for the heterodimer formed by NGFR and SORCS2. CC {ECO:0000256|ARBA:ARBA00025882}. CC -!- SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. CC {ECO:0000256|RuleBase:RU364086}. CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000256|RuleBase:RU364086}. CC -!- SIMILARITY: Belongs to the NGF-beta family. CC {ECO:0000256|ARBA:ARBA00010783, ECO:0000256|RuleBase:RU364086}.
