Protein attributes

Sequence length	249 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

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.
Subunit structure	Monomers and homodimers. Binds to NTRK2/TRKB. Ref.3
Subcellular location	Secreted.
Post-translational modification	Converted into mature BDNF by plasmin (PLG).
Sequence similarities	Belongs to the NGF-beta family.
