描述：

Complexin-1 Antibody 兔多抗可以识别内源性的complexin-1总蛋白。该抗体与complexin-2不会发生交叉反应。该单克隆抗体由合成肽段免疫动物产生，该肽段与人complexin-1蛋白Ala82附近氨基酸一致。Complexins是由氨基和羧基末端结构域的非结构的结构域包围的α螺旋结构域组成的小的可溶性蛋白(1)。这些胞浆蛋白和t-SNAREs以低亲和度结合而以高亲和性募集SNARE复合物(1,2)。神经细胞表达两种亚型(3)，complexin-1和 complexin-2，以调节诱发和自发的胞吐作用(4,5)。RNAi介导的敲除(6)或基因沉默(7)改变了complexin的表达水平导致自发融合时间和神经递质释放过程的变化，这反映complexin在一致性和刺激性神经突出中都发挥作用。

Homology

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

Specificity / Sensitivity

Complexin-1 Antibody recognizes endogenous levels of total complexin-1 protein. This antibody does not cross-react with complexin-2.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala82 of human complexin-1 protein.

Background

Complexins are small soluble proteins composed of a central α-helical-structured domain surrounded by amino- and carboxy-terminal unstructured domains (1). These cytosolic proteins bind to t-SNAREs with low affinity and to assembled SNARE complexes with high affinity (1,2). Two isoforms, complexin-1 and complexin-2, are expressed in neuronal cells (3) where they regulate evoked and spontaneous exocytosis (4,5). Altered complexin expression resulting from RNAi-mediated knockdown (6) or gene invalidation (7) leads to alteration in spontaneous fusion events and neurotransmitter release, which reflects functions at both inhibitory and stimulatory synapses.
