KRT1

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, Jul 2008]

Interaction

Heterotetramer of two type I and two type II keratins. Heterodimer with KRT10 (PubMed:27595935). Two heterodimers of KRT1 and KRT10 form a heterotetramer (PubMed:27595935). Interacts with ITGB1 in the presence of RACK1 and SRC, and with RACK1 (PubMed:17956333). Interacts with C1QBP; the association represents a cell surface kininogen receptor (PubMed:21544310). Interacts with EPPK1; interaction is dependent of higher-order structure of intermediate filament (PubMed:16923132).
