Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Arabidopsis thaliana, Cucurbita pepo
CPX1 (complexin 1) encodes a small, predominantly cytosolic neuronal protein enriched at synapses where it associates with presynaptic release sites and synaptic vesicle-proximal membranes through interactions with the assembled SNARE fusion machinery. The protein is largely helical and organized into an N-terminal region that supports evoked release, an accessory alpha-helix that can inhibit premature "zippering" of the SNARE bundle (fusion clamp activity), and a central SNARE-binding alpha-helix that docks along the SNARE complex; its C-terminal region contributes to efficient targeting/engagement near membranes and can tune inhibitory control of spontaneous fusion. Functionally, CPX1 is a key regulator of synaptic vesicle exocytosis, coupling to neuronal SNARE complexes (including syntaxin-1, SNAP25, and synaptobrevin/VAMP) to both promote fast Ca2+-triggered neurotransmitter release and suppress inappropriate spontaneous fusion by stabilizing specific prefusion SNARE states; in addition to presynaptic roles, complexin-dependent SNARE regulation has also been implicated in activity-regulated postsynaptic exocytosis events such as AMPA receptor insertion during synaptic plasticity.
