Protocols
- 8474:
- Western Blotting
Specificity / Sensitivity
Munc18-1 Antibody recognizes endogenous levels of total Munc18-1 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near Asp453 of human Munc18-1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from mouse brain, rat brain, and human cerebellum using Munc18-1 Antibody.
Background
Munc18-1 belongs to the Munc18 protein family which also includes Munc18-2 and Munc18-3. These proteins are highly conserved at the amino acid sequence level and play a critical role in membrane fusion. Munc18 proteins control SNARE complex formation (1,2) and interact with syntaxin (3). In Munc18-1 knockout mice, neurotransmitter release is completely abolished (4). In addition, Munc18-1 acts as a molecular chaperone for syntaxin-1, allowing for formation of the SNARE complex at the plasma membrane (5). Munc18-1 also acts as a regulator of vesicle docking during exocytosis (6).
