Preparation and Storage

Background: Occludin

Occludin is an integral membrane protein with an apparent molecular mass of approximately 65 kDa.  It is localized exclusively at tight junctions (TJ) of select epithelial and endothelial cells.  The protein is 522 amino acids (aa) in length and contains a cytoplasmic N-terminus, four transmembrane domains, and a long COOH‑terminal cytoplasmic domain (domain E) that contains 255 aa.  Residues 1-66 make up the first cytoplasmic domain, and that is included in the MARVEL region consisting of aa 57-210.  The MARVEL region is a membrane-associating domain that spans aa 67-243.  Of note, residues 92-131 are glycine and tyrosine rich.  Residues 244-265 constitute the last transmembrane region, with aa 266-522 representing the long cytoplasmic domain termed domain E.  At the TJ, Occludin associates with membrane peripheral protein ZO-1 (220 kDa).  Human Occludin shares 90% aa sequence identity with mouse Occludin.
