KRT20, Recombinant, Human, aa1-424aa, His-Tag (Keratin, type I cytoskeletal 20)

KRT20 is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. KRT20 is a major cellular protein of mature enterocytes and goblet cells and is specifically expressed in the gastric and intestinal mucosa. Source: Recombinant protein corresponding to aa1-424 of human KRT20, fused to His-tag at N-terminal expressed in E. coli.
