Protein attributes

Sequence length	211 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Neurotrophic factor that regulates central nervous development and function. Ref.5
Subunit structure	Homodimer. Interacts with FGFR2 and FGFR4. Affinity between fibroblast growth factors (FGFs) and their receptors is increased by heparan sulfate glycosaminoglycans that function as coreceptors. Ref.5 Ref.7
Subcellular location	Secreted Ref.3.
Tissue specificity	Predominantly expressed in the cerebellum. Ref.3
Sequence similarities	Belongs to the heparin-binding growth factors family.
