Loricrin is a protein that in humans is encoded by the LOR gene.[3][4][5]

Function

Loricrin is a major protein component of the cornified cell envelope found in terminally differentiated epidermal cells.[5]

Loricrin is expressed in the granular layer of all keratinized epithelial cells of mammals tested including oral, esophageal and stomach mucosa of rodents, tracheal squamous metaplasia of vitamin A deficient hamster and estrogen induced squamous vaginal epithelium of rats.[6]

Clinical significance

Mutations in the LOR gene are associated with Vohwinkel's syndrome and Camisa disease, both inherited skin diseases.
