1/50. Predicted molecular weight: 134 kDa.
Plays a role in tight junctions and adherens junctions.
This protein is found in epithelial cell junctions. Isoform A1 is abundant in the heart and brain. Detected in brain and skeletal muscle. It is present almost exclusively in normal tissues. Isoform C1 is expressed at high level in the kidney, pancreas, heart and placenta. Not detected in brain and skeletal muscle. Found in normal as well as in most neoplastic tissues.
Involvement in disease
Defects in TJP2 are involved in familial hypercholanemia (FHCA) [MIM:607748]. FHCA is a disorder characterized by elevated serum bile acid concentrations, itching, and fat malabsorption.
Belongs to the MAGUK family. Contains 1 guanylate kinase-like domain. Contains 3 PDZ (DHR) domains. Contains 1 SH3 domain.
Cell junction > adherens junction. Cell membrane. Cell junction > tight junction. Nucleus. Also nuclear under environmental stress conditions and in migratory endothelial cells and subconfluent epithelial cell cultures.
