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 100 µL of sterile water.
Specific Species Reactivity: Physcomitrium patens
CPX1 isoform 1 encodes a small, soluble, predominantly cytosolic presynaptic protein that is enriched in neurons and associates with sites of synaptic vesicle exocytosis through high-affinity binding to assembled/assembling SNARE complexes. Isoform 1 is a ~134 amino-acid protein organized into functionally specialized helical regions, including an N-terminal segment that promotes Ca2+-evoked neurotransmitter release, an accessory alpha-helix that contributes to suppression of premature/spontaneous fusion by restraining late SNARE "zippering," and a conserved central alpha-helix that forms the core SNARE-binding interface; its C-terminal region further supports membrane- and fusion-site engagement to tune complexin access to assembling SNAREs. Functionally, CPX1 acts as a bidirectional regulator of synaptic transmission by stabilizing an intermediate SNAREpin state that both primes vesicles for fast, Ca2+-triggered fusion and clamps fusion to limit spontaneous release, thereby sharpening the timing and reliability of neurotransmitter secretion.
