General description

Synapsin-1 (UniProt O88935; also known as Synapsin I) is encoded by the Syn1 (also known as Syn-1) gene (Gene ID 20964) in murine species. The synapins constitute a family of abundant neuronal phosphoproteins that regulate SV trafficking and neurotransmitter release at the pre-synaptic terminal. Three genes exisit in mammals, encoding altogether 11 synapsin members by alternative splicings (Synapsin Ia & Ib by SYN1, Synapsin IIa & IIb by SYN2, Synapsin IIIa through IIIf by SYN3), Syn III is the most precociously expressed isoform that has a role in the early phases of neural development and is downregulated in mature neurons. On the other hand, Syn I and Syn II are expressed at low levels at birth and their expressions progressively increase during synaptogenesis to reach a stable plateau at 1–2R01;months of life. The NH2-terminal region is divided in A, B, and C domains and is highly conserved among synapsin isoforms. Synapsins are regulated by postransloational phosphorylations. Domain A contains PKA and CaMKI/IV phosphorylation sites, domain B contains MAPK/Erk phosphorylation sites, and domain C is phosphorylated by Src. The c-terminal regions contain spliced domains and diverge among synapsin isoforms (domain D in Syn Ia and Ib, domain G in Syn IIa and IIb, domain H in Syn IIa, and domain J in Syn IIIa), although they all bear proline-rich regions binding to several SH3-containing proteins and additional phosphorylation sites for CaMKII, MAPK/Erk, and cdk1/5.
