Gene Information

human ... KRT1(3848)

General description

Keratin 1 (KRT1) is a cytoplasmic intermediate filament protein, that is expressed in the basal layer of the epidermis. This gene is located on human chromosome 12q13.
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 keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in the spinous and granular layers of the epidermis with family member KRT10 and mutations in these genes have been associated with bullous congenital ichthyosiform erythroderma. The type II cytokeratins are clustered in a region of chromosome 12q12-q13. (provided by RefSeq)

Biochem/physiol Actions

Keratin 1 (KRT1) helps to maintain skin integrity and participates in inflammatory response. It plays an important role in the differentiation and function of keratinocytes. Since KRT1 is one of the important cytoskeleton filament, it extends mechanical support and participates in additional activities in epithelial cells.
