Cytokeratin 75: Proteins and Enzymes

Keratin-75 is a protein that plays a central role in hair and nail formation, as it is an important component of the keratin intermediate filaments that are located in the companion layer of the hair follicle, and is 551 amino acids long with a weight of approximately 60 kDa. Studies are being conducted on diseases and disorders related to this protein including loose anagen hair syndrome, pseudofolliculitis barbae, histocytoma, Marek disease, dermatitis, alopecia, pharyngitis, lung cancer, breast cancer, esophagitis, hepatitis, and neuronitis. Keratin-75 has also been shown to have interactions with GABARAP, GABARAPL1, MAP1LC3A, MAR1LC3B, and AMBRA1.
