Gene Information

human ... OCLN(100506658)

General description

Occludin (OCLN) is an integral membrane protein, encoded by the gene mapped to human chromosome 5q13.2. OCLN is a ~65 kDa protein with four transmembrane domains including, a long COOH-terminal cytoplasmic domain, a short NH2-terminal cytoplasmic domain, two extracellular loops, and one intracellular turn. It is specifically localized at tight junctions (TJ).

Application

Anti-Occludin antibody from rabbit has been used in immunocytochemistry and western blotting.

Biochem/physiol Actions

Occludin (OCLN), along with tight junction (TJ)-associated peripheral membrane proteins, plays a vital role in formation and regulation of TJ. The encoded protein facilitates the translocation of p85a to TJs to regulate actin organization after oxidative stress. OCLN is also implicated in cell migration. Mutation in the gene leads to the development of band-like calcification with simplified gyration and polymicrogyria (BLC-PMG).
