Description

General description

Occludin is a 65-kDa integral plasma-membrane protein located at the tight junctions. It is required for cytokine-induced regulation of the tight junction paracellular permeability barrier. Occludin is believed to prevent the transport of macromolecules through the tight junction. Encoded by the OLCN gene, occludin spans the plasma membrane four times, forming two extracellular loops and exposing its NH2 and COOH terminus to the cytosol. This cytoplasmic tail binds directly to the ZO family of proteins, which link the protein complex to the actin cytoskeleton. Phosphorylation/dephosphorylation plays a major role in regulation of occludin and tight junctions. Expression of occludin is required for infection of liver cells by hepatitis C virus (HCV).

Specificity

This antibody recognizes the N-terminus of Occludin.

Immunogen

Epitope: N-terminus

KLH-conjugated linear peptide corresponding to the N-terminus of human Occludin.

Application

This Anti-Occludin Antibody is validated for use in Western Blotting for the detection of Occludin.

Quality

Evaluated by Western Blot in human kidney tissue lysate.

Western Blot Analysis: 0.2 µg/mL of this antibody detected Occludin in 10 µg of human kidney tissue lysate.

Target description

~63 kDa observed. The calculated molecular weight is 63 kDa, however Occludin has been shown ranging from ~55 to ~65 kDa in western blots (Florian, P., et al. (2003). Biochemical and Biophysical Research Communications. 304:5-10).
