Background

Tight junction protein ZO-1 is a protein that in humans is encoded by the TJP1 gene. It is mapped to 15q13.1. This gene encodes a protein located on a cytoplasmic membrane surface of intercellular tight junctions. The encoded protein may be involved in signal transduction at cell–cell junctions. It has been found that injected CagA associates with the epithelial tight-junction scaffolding protein TJP1 and the transmembrane protein junctional adhesion molecule, causing an ectopic assembly of tight junction components at sites of bacterial attachment, and altering the composition and function of the apical-junctional complex.

Immunogen

E.coli-derived human TJP1 recombinant protein (Position: H1178-F1527) . Human TJP1 shares 82% amino acid (aa) sequence identity with mouse TJP1.

Clonality

Polyclonal

Tissue Specificity

The alpha-containing isoform is found in most epithelial cell junctions. The short isoform is found both in endothelial cells and the highly specialized epithelial junctions of renal glomeruli and Sertoli cells of the seminiferous tubules.

Applications

Flow Cytometry, IF, IHC, ICC, WB

Field of Research

Plasma Membrane, Subcellular Markers, Tags & Cell Markers

Purification

Immunogen affinity purified.

Concentration

Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.

Form

Lyophilized

Reconstitution

Add 0.2ml of distilled water will yield a concentration of 500ug/ml.

Function

The N-terminal may be involved in transducing a signal required for tight junction assembly, while the C-terminal may have specific properties of tight junctions. The alpha domain might be involved in stabilizing junctions. Plays a role in the regulation of cell migration by targeting CDC42BPB to the leading edge of migrating cells. .
