Keratin, type II cytoskeletal 5 also known as KRT5 is a protein that in human is encoded by the KRT5 gene.[1][2][3]

Contents

Function

The protein encoded by this gene is a member of the keratin gene family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic (i.e., different types of) keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. The type II cytokeratin genes are clustered in a region of chromosome 12q12-q13.

This type II cytokeratin is specifically expressed in the basal layer of the epidermis with family member KRT14.

Clinical significance

Mutations in these genes have been associated with a complex of diseases termed epidermolysis bullosa simplex.[4]

Interactions

Keratin 5 has been shown to interact with ALOX12.[5]
