描述：

SNAP25 (A195) Antibody 兔多抗识别内源性的SNAP25总蛋白。该多克隆抗体由合成的人类SNAP25蛋白Ala195位点附近肽段免疫动物而制成。该抗体使用蛋白A和多肽亲和层析纯化而得。25kDa的突触相关蛋白（SNAP25）是一个膜可溶性的、N-乙基马来酰亚胺敏感因子，可附着蛋白受体（T-SNARE），在神经元突触前膜被发现。SNAP25与SNARE蛋白syntaxin和synaptobrevin形成一个核心复合物，介导Ca2+依赖性胞吐时突触囊泡与质膜的融合（1）。这种复合物与神经递质γ-氨基丁酸（GABA）的胞外分泌的很有关。神经递质的释放可以被肉毒杆菌毒素A和E蛋白裂解SNAP25所抑制（2）。SNAP25在内体融合中和Q-SNARE类似起着次要的作用；该蛋白与注意缺陷多动障碍（ADHD）的遗传易感性相关（3）。

Homology

Species predicted to react based on 100% sequence homology: Human

Specificity / Sensitivity

SNAP25 (A195) Antibody detects endogenous levels of total SNAP25 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala195 of human SNAP25. Antibodies are purified by protein A and peptide affinity chromatography.

Background

The 25 kDa synaptosome-associated protein (SNAP25) is a target membrane soluble, N-ethylmaleimide-sensitive factor attachment protein receptor (t-SNARE) that is found on neuronal presynaptic membranes. SNAP25 forms a core complex with the SNARE proteins syntaxin and synaptobrevin to mediate synaptic vesicle fusion with the plasma membrane during Ca2+-dependent exocytosis (1). This complex is responsible for exocytosis of the neurotransmitter γ-aminobutyric acid (GABA). Neurotransmitter release is inhibited by proteolysis of SNAP25 by botulinum toxins A and E (2). SNAP25 plays a secondary role as a Q-SNARE involved in endosome fusion; the protein is associated with genetic susceptibility to attention-deficit hyperactivity disorder (ADHD) (3).
