      Background InformationClaudin-2 (UniProt: P57739; also known as SP82) is encoded by the CLDN2 (also known as PSEC0059, SP82, UNQ705/PRO1356) gene (Gene ID: 9075) in human. Claudin-2 is a multi-pass membrane protein with three cytoplasmic domains, two extracellular domains, and four transmembrane domains. It can exist as homopolymer or as a heteropolymer with other claudins mediated through the first extracellular domain (aa 29-81). These interactions are achieved largely through electrostatic interactions with Asp65 and with somewhat weaker interaction with electrons of the Tyr67. Claudin-2 is expression has been reported in liver, kidney, and small intestine. It is a component of epithelial tight junctions (TJ) that plays a key role in TJ-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity. Its expression is shown to be enhanced in subjects with inflammatory bowel disease. Treatment with TNF-a is also reported to upregulate the expression of Claudin-2 via PI3-kinase signaling that reduces transepithelial electrical resistance (TEER). Clone 1A2 is shown to reduce TNF-a-induced reduction in TEER and restore TJ integrity. (Ref.: Takigawa, M., et al. (2017). J. Pharmacol. Exp. Ther. 363(3); 444-451).
