Research Backgrounds

Function:

May play a role in the formation and regulation of the tight junction (TJ) paracellular permeability barrier. It is able to induce adhesion when expressed in cells lacking tight junctions.

PTMs:

Dephosphorylated by PTPRJ. The tyrosine phosphorylation on Tyr-398 and Tyr-402 reduces its ability to interact with TJP1. Phosphorylation at Ser-490 also attenuates the interaction with TJP1.

Subcellular Location:

Cell membrane>Multi-pass membrane protein. Cell junction>Tight junction.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Localized at tight junctions of both epithelial and endothelial cells. Highly expressed in kidney. Not detected in testis.

Subunit Structure:

Interacts with TJP1/ZO1. Interacts with VAPA. Interacts with CLDN1, CLDN6, CLDN9, CLDN11, CLDN12 and CLDN17.

Family&Domains:

The C-terminal is cytoplasmic and is important for interaction with ZO-1. Sufficient for the tight junction localization. Involved in the regulation of the permeability barrier function of the tight junction (By similarity). The first extracellular loop participates in an adhesive interaction.

Belongs to the ELL/occludin family.
