General annotation (Comments)

Function

Neuronal phosphoprotein that coats synaptic vesicles, binds to the cytoskeleton, and is believed to function in the regulation of neurotransmitter release By similarity.

Subunit structure

Interacts with CAPON. Ref.3

Subcellular location

Cell junction › synapse.

Sequence similarities

Belongs to the synapsin family.
