Occludin (1A8) Anti-Rat Mouse IgM MoAb

Occludin is an approximately 60kDa-integral membrane protein localizing at Tight-Junction, and composed of short N-terminal cytosolic domain, four transmembrane domains and long C-terminal cytosolic domain. It is reported that Occludin has no homology to claudin family and forms strand by coporimerization with claudin family proteins. It is considered that Tight-Junction plays an important role in maintenance of cellular polarity (fence function) and in regulating the passage of ions and small molecular through the paracellular pathway (barrier function).
