Claudin
Claudins are a family of proteins that are the most important components of the tight junctions, where they establish the paracellular barrier that controls the flow of molecules in the intercellular space between the cells of an epithelium. They have four transmembrane domains, with the N-terminus and the C-terminus in the cytoplasm.
Famous quotes containing the word claudin:
“You’ll stay here with me my child, won’t you? It’s been so lonely without you. But you’ve come to me at last, haven’t you? Now you’ll sing for me and I’ll play and we’ll be together forever.”
—Eric Taylor, and Leroux. Arthur Lubin. Erique Claudin (Claude Rains)
