Beschreibung

General description

Munc-18-1 (67 kDa) is an abundant neuronal protein that tightly binds to the synaptic fusion protein syntaxin. It is primarily expressed in neuronal tissues. Both Munc-18-1 and 2 isoforms bind tightly to syntaxins 1A, 2, and 3.

Immunogen

synthetic peptide corresponding to amino acids 577-594 located at the C-terminus of rat Munc-18-1 conjugated to KLH. This sequence is identical in mouse, chicken, bovine, and human Munc-18-1. It does not share homology with the Munc-18-2 and Munc-18-3 isoforms.

Application

Anti-Munc-18-1 antibody produced in rabbit has been used in immunoblotting and immunofluorescence.

Biochem/physiol Actions

Munc-18-1 functions in synaptic vesicle exocytosis. It modulates neurotransmission by associating with syntaxin 1. Munc-18-1 binds to both syntaxin 1A and 1B isoforms, inhibiting the binding of t-soluble N-ethylmaleimide-sensitive factor-attached protein receptor (SNARE) synaptobrevin/vesicle-associated membrane protein (VAMP) and SNAP25 to syntaxin 1 and preventing SNARE assembly. Munc-18 is required for neurotransmitter secretion from synaptic vesicles throughout development and has been implicated in axonal branching in hippocampal neurons.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
