Synaptotagmin 1 (Syt1) belongs to a family with 17 members. Synaptotagmins are all single-pass transmembrane proteins containing two domains binding to calcium at their intracellular portion.  Synaptotagmin 1 is enriched at the pre-synaptic boutons on axon terminals, associated with synaptic vesicles, and is implicated in triggering vesicle fusion and neurotransmitter release upon a local increase of calcium concentration.

Our nanobody recognizes strongly and specifically the cytosolic portion of Syt1.
