Keratin 5 Keratin 5 Keratin 5, also known as KRT5, K5, or CK5, is a protein that is encoded in humans by the "KRT5" gene. It dimerizes with keratin 14 and forms the intermediate filaments (IF) that make up the cytoskeleton of basal epithelial cells. This protein is involved in several diseases including epidermolysis bullosa simplex and breast and lung cancers. Keratin 5, like other members of the keratin family, is an intermediate filament protein. These polypeptides are characterized by a 310 residue central rod domain that consists of four alpha helix segments (helix 1A, 1B, 2A, and 2B) connected by three
Myosin light chain nodes to migrate into inflammatory sites in an S1PR1-dependent manner." The proposed mechanisms of action of CD69/Myl9/12 system are related to the regulation of airway inflammatory processes and thus can prove to be a novel therapeutic target for chronic inflammatory diseases, in general . Myosin light chain A myosin light chain is a light chain (small polypeptide subunit) of myosin. Myosin light chains were discovered by Chinese biochemist Cao Tianqin (Tien-chin Tsao) when he was a graduate student at the University of Cambridge in England. Structurally, myosin light chains belong to the EF-hand family, a large family of Ca- binding
