紧密连接蛋白7抗体概述：

B淋巴细胞在抗原的刺激下，能够分化、增殖形成具有针对这种抗原分泌特异性抗体的能力。B细胞的这种能力和量是有限的，不可能持续分化增殖下去，因此产生免疫球蛋白的能力也是极其微小的。将这种B细胞与非分泌型的骨髓瘤细胞融合形成杂交瘤细胞，再进一步克隆化，这种克隆化的杂交瘤细胞是既具有瘤细胞的无限分裂的能力，又具有产生特异性抗体的B淋巴细胞的能力。将这种克隆化的杂交瘤细胞进行培养或注入小鼠腹水内即可获得大量的高效、单一的特异性抗体。这种技术即称为单克隆抗体技术。

产品介绍 The Claudin superfamily consists of many structurally related proteins in humans (1). These proteins are important structural and functional components of tight junctions in paracellular transport (1,2). Claudins are located in both epithelial and endothelial cells in all tight junction-bearing tissues (1). Three classes of proteins are known to localize to tight junctions, including the Claudins, Occludin and Junction adhesion molecule (3). Claudins, which consist of four transmembrane domains and two extracellular loops make up tight junction strands (4). Claudin expression is highly restricted to specfic regions of different tissues and may have an important role in transcellular transport through tight junctions (5). mRNA studies indicate that Claudin-7 is specifically expressed in mouse lung and kidney, but not in heart, brain, spleen, liver, skeletal muscle or testis (6). The gene encoding human Claudin-7 maps to chromosome 17p13 (7).

Function : Plays a major role in tight junction-specific obliteration of the intercellular space.

Subunit : Directly interacts with TJP1/ZO-1, TJP2/ZO-2 and TJP3/ZO-3 (By similarity). The phosphorylated form interacts with EPCAM.

Subcellular Location : Cell membrane. Lateral cell membrane. Cell junction > tight junction. Co-localizes with EPCAM at the lateral cell membrane and tight junction.

Tissue Specificity : Expressed in kidney, lung and prostate. Isoform 1 seems to be predominant, except in some normal prostate samples, where isoform 2 is the major form. Down-regulated in breast cancers, including ductal carcinoma in situ (DCIS), lobular carcinoma in situ (LCIS) and invasive ductal carcinoma (IDC) (at protein level), as well as in several cancer cell lines. Loss of expression correlates with histological grade, occurring predominantly in high-grade lesions.

紧密连接蛋白7抗体Post-translational modifications : Phosphorylated.

Similarity : Belongs to the claudin family.
