General description

Anti-MUNC-18A Antibody detects endogenous levels of total MUNC-18A protein.

The gene STXBP1 (syntaxin binding protein 1) is mapped to human chromosome 9q34.1. The encoded protein is 594 amino acids long, which is expressed in all tissues with highest levels in retina and cerebellum.


The antiserum was produced against synthesized peptide derived from human MUNC-18a.

Immunogen Range: 279-328

Physical form

Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.

Biochem/physiol Actions

The gene STXBP1 (syntaxin binding protein 1) encodes a regulatory protein of the components of the SNARE (soluble NSF/ N-ethylmaleimide-sensitive factor attachment protein receptor) complex that are crucial for neurotransmission. It is a neuronal protein that functions in synaptic vesicle release. Mutations in this gene have been associated with early infantile epileptic encephalopathy. It causes autosomal dominant mental retardation and nonsyndromic epilepsy.
