描述：

EEA1 Antibody抗体识别内源性的EEA1总蛋白。
多克隆抗体用与人类EEA1中Gly14位点附近的氨基酸序列对应的人工合成肽段免疫动物而制成。该抗体使用蛋白亲和层析纯化而得。EEA1是一个早期内涵体标志物，也是Rab5效应蛋白，对内涵体膜融合和转运至关重要（1-2）。EEA1羧基末端包括一个FYVE结构域，可以结合到磷脂酰肌醇-3-磷酸酯（PtdIns(3)P），将EEA1定位到早期内体（3）。EEA1与内体膜的稳定结合由PI3激酶、Rab5和钙/钙调蛋白（4-6）。一旦到膜上，EEA1就能与Rab5、NSF和syntaxin 13相互作用，促进早期内体膜的锚定与融合（7）。

原厂资料：

Specificity / Sensitivity

EEA1 Antibody detects endogenous levels of total EEA1 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly14 of human EEA1 protein. Antibodies are purified by peptide affinity chromatography.

Background

EEA1 is an early endosomal marker and a Rab5 effector protein essential for early endosomal membrane fusion and trafficking (1-2). The carboxy terminus of EEA1 contains a FYVE domain which binds to phosphatidylinositol-3-phosphate (PtdIns(3)P), targeting EEA1 to early endosomes (3). The stable association of EEA1 with the endosomal membrane is regulated by PI3 kinase, Rab5 and calcium/calmodulin (4-6). Once on the membrane, EEA1 interacts with Rab5, NSF and syntaxin 13 to promote early endosomal membrane docking and fusion (7).
