Keratin 5, also known as KRT5, K5, or CK5, is a protein that is encoded in humans by the KRT5 gene.[5][6][7] It dimerizes with keratin 14 and forms the intermediate filaments (IF) that make up the cytoskeleton of basal epithelial cells.[8][9] This protein is involved in several diseases including epidermolysis bullosa simplex and breast and lung cancers.[9][10][11]
