Keratin 15
Keratin 15 is a protein that in humans is encoded by the KRT15 gene. It has also been referred to as cytokeratin 15, K1CO and KRTB.
Keratin 15 is a type I cytokeratin. It is well-expressed in the basal layer of stratified [epithelium (disambiguation)|complex epithelia]. However, acral keratinocytes express little to no keratin 15.
