|Description||Cytokeratin 20 is a type I keratin which is primarily expressed in gastric and intestinalepithelium, urothelium, and Merkel-cells. The keratins are intermediate filament proteinsresponsible for the structural integrity of epithelial cells and are subdivided intocytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which arearranged in pairs of heterotypic keratin chains. Their genes are clustered in a region ofchromosome 17q12-q21. Cytokeratin 20 is a major cellular protein of mature enterocytesand goblet cells and is specifically expressed in the gastric and intestinal mucosa. It isalso expressed in adenocarcinomas of the colon, stomach, pancreas and the bile systemand is present in mucinous ovarian tumors, transitional-cell and Merkel-cell carcinomas. Notably, the squamous cell carcinomas and adenocarcinomas of the breast, lung, andendometrium, non-mucinous tumors of the ovary, and small cell carcinomas lackcytokeratin 20.|
