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.
