Claudin18.2 also known as claudin 18 CLDN18 or claudin-18.2 is a tight junction protein with a molecular mass of approximately 27 kDa. It is primarily expressed in gastric epithelial cells and certain lung tissues. Claudin18.2 is part of the claudin family which plays a critical role in forming tight junctions to regulate paracellular transport and maintain cellular polarity. This isoform specifically expressed in the stomach is encoded by the CLDN18 gene located on chromosome 3. Researchers often use techniques like Immunohistochemistry (IHC) referred to as claudin 18.2 IHC or cldn18 IHC to study its expression and localization.
Biological function summary

Claudin18.2 functions within tight junction complexes creating a barrier and controlling the movement of ions and molecules between cells. It is vital for the integrity and function of epithelial cell barriers in the stomach. The protein interacts with other claudins and cytoplasmic proteins to form these tight junctions essential for maintaining tissue organization and permeability. Its unique expression pattern makes it a significant marker for gastric tissue and a potential target for therapeutics.

Pathways

Claudin18.2 is involved in cellular pathways related to adhesion and barrier function. It plays a role in the tight junction pathway critical for epithelial barrier integrity. This pathway involves interactions with other claudin proteins and ZO-1 which is a cytoplasmic plaque protein that links claudins to the actin cytoskeleton reinforcing cellular structure. Another pathway where claudin18.2 is important is the gastro-intestinal epithelium maintenance pathway which is fundamental for protecting gastric tissues.

Claudin18.2 is a notable target in cancers especially gastric cancer. Its specific expression in gastric tissues makes it an attractive target for cancer immunotherapy as aberrant expression could indicate gastric cancer onset. Another disorder related to claudin18.2 is asthma particularly where lung epithelial cells express this protein. Studies have identified links between claudin18.2 and increased permeability in lung tissues implicating it in asthmatic pathophysiology. Its association with these conditions highlights the potential for claudin18.2 as a diagnostic or therapeutic target in oncology and respiratory diseases.

Target data

Involved in alveolar fluid homeostasis via regulation of alveolar epithelial tight junction composition and therefore ion transport and solute permeability, potentially via downstream regulation of the actin cytoskeleton organization and beta-2-adrenergic signaling (By similarity). Required for lung alveolarization and maintenance of the paracellular alveolar epithelial barrier (By similarity). Acts to maintain epithelial progenitor cell proliferation and organ size, via regulation of YAP1 localization away from the nucleus and thereby restriction of YAP1 target gene transcription (By similarity). Acts as a negative regulator of RANKL-induced osteoclast differentiation, potentially via relocation of TJP2/ZO-2 away from the nucleus, subsequently involved in bone resorption in response to calcium deficiency (By similarity). Mediates the osteoprotective effects of estrogen, potentially via acting downstream of estrogen signaling independently of RANKL signaling pathways (By similarity).. Isoform A1. Involved in the maintenance of homeostasis of the alveolar microenvironment via regulation of pH and subsequent T-cell activation in the alveolar space, is therefore indirectly involved in limiting C.neoformans infection.. Isoform A2. Required for the formation of the gastric paracellular barrier via its role in tight junction formation, thereby involved in the response to gastric acidification.
