General description

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target description

Synapsin-1 (UniProt: P17600; also known as Brain protein 4.1, Synapsing I) is encoded by the SYN1 gene (Gene ID: 6853) in human. Synapsins are abundant phosphoproteins expressed primarily in the brain. Synapsins I and II are expressed at the highest levels and are specifically localized to presynaptic terminals, whereas synapsin III is expressed at very low levels and is also found in cell bodies and growth cones. Synapsins I and II are expressed at low levels at birth and their expressions progressively increase during synaptogenesis to reach a stable plateau at 1-2 months of life. The N-terminal region of all synapsin have highly conserved domains A-C, while the domains D-J in the C-terminal region differ between isoforms. Domain A is shown to interact with phospholipids and this interaction is neutralized by phosphorylation of a serine by PKA and CaM Kinase I. Domain B connects domains A and C. Domain C displays most extensive homology across synapsins and mediates many of the core functions of synapsins. Synapsin I is a homodimeric protein that is present in all nerve terminals and is associated with synaptic vesicles, located at the cytoplasmic face of these vesicles. It is involved in the regulation of neurotransmitter release. In the resting state dephospho-synapsin I bind to the transmitter vesicle and reduces the availability of vesicle to fuse with presynaptic membrane. However, in the stimulated state, phosphorylated synapsin I can achieve a fusion-ready state. Synapsin I is shown to be a substrate for at least four different protein kinases and phosphorylation at serine 9 is reported to dissociate synapsin from synaptic vesicles. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
