The role and mechanism of claudins in cancer
Frontiers in Oncology, 2022 Claudins are a tetraspan membrane protein multigene family that plays a structural and functional role in constructing tight junctions. Claudins perform crucial roles in maintaining cell polarity in epithelial and endothelial cell sheets and controlling ...

Role of Stress on Driving the Intestinal Paracellular Permeability
Current Issues in Molecular Biology, 2023 The gut epithelium is a polarized monolayer that exhibits apical and basolateral membrane surfaces. Monolayer cell components are joined side by side via protein complexes known as tight junction proteins (TJPs), expressed at the most apical extreme of ...

Pharmaceutics, 2023 Claudins regulate paracellular permeability, contribute to epithelial polarization and are dysregulated during inflammation and carcinogenesis. Variants of the claudin-binding domain of Clostridium perfringens enterotoxin (cCPE) are highly sensitive ...

Claudins in teleost fishes [PDF]
Tissue Barriers, 2013 Teleost fishes are a large and diverse animal group that represent close to 50% of all described vertebrate species. This review consolidates what is known about the claudin (Cldn) family of tight junction (TJ) proteins in teleosts. Cldns are transmembrane proteins of the vertebrate epithelial/endothelial TJ complex that largely determine TJ ...

Toxins, 2010 Clostridium perfringens enterotoxin (CPE), a major cause of food poisoning, forms physical pores in the plasma membrane of intestinal epithelial cells. The ability of CPE to recognize the epithelium is due to the C-terminal binding domain, which binds to

Role of TM3 in claudin-15 strand flexibility: A molecular dynamics study
Frontiers in Molecular Biosciences, 2022 Claudins are cell-cell adhesion proteins within tight junctions that connect epithelial cells together. Claudins polymerize into a network of strand-like structures within the membrane of adjoining cells and create ion channels that control paracellular ...

The food contaminant deoxynivalenol, decreases intestinal barrier permeability and reduces claudin expression [PDF]
, 2009 The gastrointestinal tract represents the first barrier against food contaminants as well as the first target for these toxicants. Deoxynivalenol (DON) is a mycotoxin that commonly contaminates cereals and causes various toxicological effects.

SUMOylation of claudin-2: SUMOylation of claudin-2 [PDF]
Annals of the New York Academy of Sciences, 2012 The C‐terminal cytoplasmic tails of claudins are likely sites for interaction with proteins that regulate their function. We performed a yeast two‐hybrid screen with the tail of human claudin‐2 against a human kidney cDNA library and identified interactions with the PDZ3 domain of ZO‐2 as well as ubiquitin‐conjugating enzyme E2I (SUMO ligase‐1) and E3 ...

Frontiers in Genetics, 2023 The claudin multigene family is associated with various aberrant physiological and cellular signaling pathways. However, the association of claudins with survival prognosis, signaling pathways, and diagnostic efficacy in colon cancer remains poorly ...

Journal of the American Society of Nephrology, 2015 Claudins are tight-junction membrane proteins that function as both pores and barriers in the paracellular pathway in epithelial cells. In the kidney, claudins determine the permeability and selectivity of different nephron segments along the renal tubule. In the proximal tubule, claudins have a role in the bulk reabsorption of salt and water.
