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.

Subunit structure

Homodimer By similarity. Interacts with CAPON. Forms a ternary complex with NOS1. Isoform Ib interacts with PRNP By similarity. Ref.6

Subcellular location

Cell junctionsynapse. Golgi apparatus By similarity.

Post-translational modification

Substrate of at least four different protein kinases. It is probable that phosphorylation plays a role in the regulation of synapsin-1 in the nerve terminal By similarity.

Sequence similarities

Belongs to the synapsin family.

Sequence caution

The sequence CAA28353.1 differs from that shown. Reason: Sequencing errors.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform IA (identifier: P09951-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform IB (identifier: P09951-2)

The sequence of this isoform differs from the canonical sequence as follows:
     660-668: NKSQSLTNA → KASPAQAQP
     669-704: Missing.
