Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name Munc13 (Pan) (UNC13B Antibody Abstract)
Background Release of neurotransmitters at the synaptic junction is a primary mechanism of neuronal communication and is regulated by the synaptic vesicle (SV) cycle. Several components of the SV cycle were initially characterized in C. elegans. One of those, unc-13, is involved in normal presynaptic function. Mammalian homologues of unc-13 are Munc13-1, 13-2, and 13-3. These neuron-specific proteins lack N-terminal homology, but are highly conserved in their C-terminal regions. Here they contain a phorbal ester binding C1-domain and two C2-domains with homology to the PKC Ca2+/phospholipid-binding domain. The most abundant isoform, Munc 13-1, is a presynaptic receptor with high affinities for phorbol ester and DAG. In response to phorbol ester, Munc13-1 associates with the plasma membrane and acts as a stimulation dependent enhancer of neurotransmitter release. In addition, Munc13-1 interacts with components of the SV cycle (syntaxin, SNAP25, synaptobrevin, Doc2) and with a brain specific isoform of beta-spectrin, a protein that interacts with the actin cytoskeleton. Thus, it is thought that Munc13 proteins function in signaling pathways that regulate the neuronal exocytic machinery.
