重组人突触相关蛋白25B

产品英文名称：
Recombinant Synaptosomal-associated protein 25kDa， C.elegans

英文简称:
SNAP-25

中文名称:
重组线虫突触相关蛋白25kDa

背景资料:
Synaptic vesicle membrane docking and fusion is mediated by SNAREs （soluble N-ethylmaleimide-sensitive factor attachment protein receptors） located on the vesicle membrane （v-SNAREs） and the target membrane （t-SNAREs）. The assembled v-SNARE/t-SNARE complex consists of a bundle of four helices， one of which is supplied by v-SNARE and the other thrRecombinant C.elegans SNAP-25 produced in E.Coli is a single， non-glycosylated polypeptide chain containing 207 amino acids and having a molecular mass of 23kDa. SNAP-25 gene was amplified by PCR from C.elegans and cloned into an E. coli expression vector. SNAP-25 was purified by using conventional chromatography techniques. by t-SNARE. For t-SNAREs on the plasma membrane， the protein syntaxin supplies one helix and the protein encoded by this gene contributes the other two. Therefore， SNAP25 product is a presynaptic plasma membrane protein involved in the regulation of neurotransmitter release. The synaptosomal-associated protein （SNAP-25） is an essential component of the core complex that mediates presynaptic vesicle tra大肠杆菌中重组表达icking. Thus， SNAP-25 is directly involved in the release of neurotransmitters.
