PA5-29463 targets Cytokeratin 4 in IHC (P) and WB applications and shows reactivity with Human samples.
The PA5-29463 immunogen is recombinant protein fragment corresponding to a region within amino acids 317 and 505 of Human Cytokeratin 4.
The protein encoded by this gene is a member of the keratin gene family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in differentiated layers of the mucosal and esophageal epithelia with family member KRT13. Mutations in these genes have been associated with White Sponge Nevus, characterized by oral, esophageal, and anal leukoplakia. The type II cytokeratins are clustered in a region of chromosome 12q12-q13.
