| Short Name | Claudin14 |
| description | Claudins form the paracellular tight junction seal in epithelial tissues. In humans, 24 claudins (claudin 1-24) have been identified. Their ability to polymerise and form strands is affected by the cell types [, , ]. They can also form heteropolymers with each other within and between tight junction strands []. Most of the claudins (claudin-12 being the exception) have a C-terminal PDZ-binding motif that can interact with other PDZ domain proteins, such as scaffolding protein, ZO-1, -2 and -3 []. They also interact with non-tight junction proteins, such as cell adhesion proteins EpCam and tetraspanins and the signaling proteins, ephrin A and B and their receptors, EphA and EphB [].Claudin-14 was identified through cDNA database searching, pursuingsequences similar to other claudin family members []. Human and mouseisoforms have been cloned. Claudin-14 shares ~25-45% overall similarity withother claudin family members at the amino acid level, displaying highestsimilarity to claudin-4. |
