Claudins are a family of proteins which, along with occludin, are the most important components of the tight junctions. Tight junctions 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.

Claudin-1 is a protein that in humans is encoded by the CLDN1 gene. It belongs to the group of claudins.

Tight junction protein ZO-2 is a protein that in humans is encoded by the TJP2 gene.

Claudin 4, also known as CLDN4, is a protein which in humans is encoded by the CLDN4 gene. It belongs to the group of claudins.

Claudin-5 is a protein that in humans is encoded by the CLDN5 gene. It belongs to the group of claudins.

Claudin 3, also known as CLDN3, is a protein which in humans is encoded by the CLDN3 gene. It is a member of the claudin protein family.

Claudin-7 is a protein that in humans is encoded by the CLDN7 gene. It belongs to the group of claudins.

Claudin-6 is a protein that in humans is encoded by the CLDN6 gene. It belongs to the group of claudins. The knockout mice of mouse homolog exhibit no phenotype, indicating that claudin-6 is dispensable for normal development and homeostasis.

Claudin-2 is a protein that in humans is encoded by the CLDN2 gene. It belongs to the group of claudins.

Claudin-12 is a protein that in humans is encoded by the CLDN12 gene. It belongs to the group of claudins.

Claudin-16 is a protein that in humans is encoded by the CLDN16 gene. It belongs to the group of claudins.

Claudin-14 is a protein that in humans is encoded by the CLDN14 gene. It belongs to a related family of proteins called claudins.

Claudin-9 is a protein that in humans is encoded by the CLDN9 gene. It belongs to the group of claudins.

Claudin-17 is a protein that in humans is encoded by the CLDN17 gene. It belongs to the group of claudins. It forms anion-selective paracellular channels and is localized mainly in kidney proximal tubules.

Claudin-10 is a protein that in humans is encoded by the CLDN10 gene. It belongs to the group of claudins.

Claudin-15 is a protein that in humans is encoded by the CLDN15 gene. It belongs to the group of claudins. Among its related pathways are Blood-Brain Barrier and Immune Cell Transmigration: VCAM-1/CD106 Signaling Pathways and Tight junction. GO annotations related to this gene include identical protein binding and structural molecule activity. An important paralog of this gene is CLDN10.

Claudin-19 is a protein that in humans is encoded by the CLDN19 gene. It belongs to the group of claudins. Claudin-19 has been implicated in magnesium transport.

Claudin-20 is a protein that in humans is encoded by the CLDN20 gene. It belongs to the group of claudins.

Claudin-18 is a protein that in humans is encoded by the CLDN18 gene. It belongs to the group of claudins.

Claudin-22 is a protein that in humans is encoded by the CLDN22 gene. It belongs to the group of claudins.
