Pan Cytokeratin

Keratin / Cytokeratin

Cytokeratins are proteins of keratin-containing intermediate filaments found in the intracytoplasmic cytoskeleton of epithelial tissue. The term "cytokeratin" began to be used in the late 1970s (for example, see "Intermediate-sized filaments of human endothelial cells" by Franke, Schmid, Osborn and Weber) when the protein subunits of keratin intermediate filaments inside cells were first being identified and characterized. In 2006 a new systematic nomenclature for keratins was created and now the proteins previously called "cytokeratins" are simply called keratins.

There are two types of cytokeratins: the basic type I cytokeratins and the acidic or neutral type II cytokeratins. Cytokeratins are usually found in pairs comprising a type I cytokeratin and a type II cytokeratin. Basic or neutral cytokeratins include CK1, CK2, CK3, CK4, CK5, CK6, CK7, and CK8. Acidic cytokeratins are CK9, CK10, CK12, CK13, CK14, CK16, CK17, CK18, CK19 and CK20. The cytokeratins can be divided into low versus high molecular weight solely based on their molecular weight. Expression of these cytokeratins is frequently organ or tissue specific. As an example, CK7 is typically expressed in the ductal epithelium of the genitourinary (GU) tract and CK20 most commonly in the gastrointestinal (GI) tract. Anatomic pathologists employ such distinctions to detect the cell of origin of various tumors.
