== Function ==
[https://www.uniprot.org/uniprot/SYN1_BOVIN SYN1_BOVIN] Neuronal phosphoprotein that coats synaptic vesicles, binds to the cytoskeleton, and is believed to function in the regulation of neurotransmitter release. The complex formed with NOS1 and CAPON proteins is necessary for specific nitric-oxid functions at a presynaptic level (By similarity).

== Publication Abstract from PubMed ==
Synapsins are abundant synaptic vesicle proteins with an essential regulatory function in the nerve terminal. We determined the crystal structure of a fragment (synC) consisting of residues 110-420 of bovine synapsin I; synC coincides with the large middle domain (C-domain), the most conserved domain of synapsins. SynC molecules are folded into compact domains and form closely associated dimers. SynC monomers are strikingly similar in structure to a family of ATP-utilizing enzymes, which includes glutathione synthetase and D-alanine:D-alanine ligase. SynC binds ATP in a Ca2+-dependent manner. The crystal structure of synC in complex with ATPgammaS and Ca2+ explains the preference of synC for Ca2+ over Mg2+. Our results suggest that synapsins may also be ATP-utilizing enzymes.

Synapsin I is structurally similar to ATP-utilizing enzymes.,Esser L, Wang CR, Hosaka M, Smagula CS, Sudhof TC, Deisenhofer J EMBO J. 1998 Feb 16;17(4):977-84. PMID:9463376<ref>PMID:9463376</ref>
