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 By similarity.

Subcellular location

Cell junctionsynapse.

Tissue specificity

Expressed exclusively in neuronal cells. Ref.3

Domain

The A region binds phospholipids with a preference for negatively charged species By similarity.

Post-translational modification

Phosphorylation at Ser-10 dissociates synapsins from synaptic vesicles By similarity.

Sequence similarities

Belongs to the synapsin family.

Sequence caution

The sequence AAH66004.1 differs from that shown. Reason: Erroneous initiation.

The sequence AAH85129.1 differs from that shown. Reason: Erroneous initiation.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform IIa (identifier: Q64332-1)

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 IIb (identifier: Q64332-2)

The sequence of this isoform differs from the canonical sequence as follows:
     459-479: GPGQPQGMQPPGKVLPPRRLP → CLQYILDCNGIAVGPKQVQAS
     480-586: Missing.
