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.

Immunogen

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

Immunogen Range: 279-328

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.

We sequenced genes coding for components of the SNARE complex (STX1A, VAMP2, SNAP25) and their regulatory proteins (STXBP1/Munc18-1, SYT1), which are essential for neurotransmission, in 95 patients with idiopathic mental retardation. We identified de novo mutations in STXBP1 (nonsense, p.R388X;

Early infantile epileptic encephalopathy with suppression-burst (EIEE), also known as Ohtahara syndrome, is one of the most severe and earliest forms of epilepsy. Using array-based comparative genomic hybridization, we found a de novo 2.0-Mb microdeletion at 9q33.3-q34.11 in a girl

In a screen designed to identify genes expressed preferentially in retina, we identified a cDNA encoding the human ortholog of rat STXBP1 (n-Sec1, Munc-18-1, rbSec1), a protein implicated in vesicle trafficking and neurotransmitter release. This protein also has similarity to
