Summaries for KRT1 Gene

Entrez Gene Summary for KRT1 Gene

  • 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]

GeneCards Summary for KRT1 Gene

KRT1 (Keratin 1) is a Protein Coding gene. Diseases associated with KRT1 include ichthyosis, cyclic, with epidermolytic hyperkeratosis and palmoplantar keratoderma, nonepidermolytic. Among its related pathways are Corticotropin-releasing hormone and Cytoskeleton remodeling Neurofilaments. GO annotations related to this gene include receptor activity and carbohydrate binding. An important paralog of this gene is KRT73.

UniProtKB/Swiss-Prot for KRT1 Gene

  • May regulate the activity of kinases such as PKC and SRC via binding to integrin beta-1 (ITB1) and the receptor of activated protein C kinase 1 (RACK1). In complex with C1QBP is a high affinity receptor for kininogen-1/HMWK.

  • Epidermolytic hyperkeratosis (EHK) [MIM:113800]: An autosomal dominant skin disorder characterized by widespread blistering and an ichthyotic erythroderma at birth that persist into adulthood. Histologically there is a diffuse epidermolytic degeneration in the lower spinous layer of the epidermis. Within a few weeks from birth, erythroderma and blister formation diminish and hyperkeratoses develop. {ECO:0000269 PubMed:10232403, ECO:0000269 PubMed:10688370, ECO:0000269 PubMed:10844506, ECO:0000269 PubMed:11531804, ECO:0000269 PubMed:12406348, ECO:0000269 PubMed:1380725, ECO:0000269 PubMed:1381288, ECO:0000269 PubMed:21271994, ECO:0000269 PubMed:7507151, ECO:0000269 PubMed:7507152, ECO:0000269 PubMed:7512983, ECO:0000269 PubMed:9856846}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Ichthyosis annular epidermolytic (AEI) [MIM:607602]: A skin disorder resembling bullous congenital ichthyosiform erythroderma. Affected individuals present with bullous ichthyosis in early childhood and hyperkeratotic lichenified plaques in the flexural areas and extensor surfaces at later ages. The feature that distinguishes AEI from BCIE is dramatic episodes of flares of annular polycyclic plaques with scale, which coalesce to involve most of the body surface and can persist for several weeks or even months. {ECO:0000269 PubMed:10053007, ECO:0000269 PubMed:10597140}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Ichthyosis hystrix, Curth-Macklin type (IHCM) [MIM:146590]: A genodermatosis with severe verrucous hyperkeratosis. Affected individuals manifest congenital verrucous black scale on the scalp, neck, and limbs with truncal erythema, palmoplantar keratoderma and keratoses on the lips, ears, nipples and buttocks. {ECO:0000269 PubMed:11286616}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Keratoderma, palmoplantar, non-epidermolytic (NEPPK) [MIM:600962]: A dermatological disorder characterized by well-demarcated hyperkeratosis is present over the palms and soles. A red band is frequently present at the periphery of the keratosis. It is usually non-transgredient, with a sharp demarcation of the lesions at the wrists. {ECO:0000269 PubMed:11286630, ECO:0000269 PubMed:7528239}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Keratoderma, palmoplantar, striate 3 (SPPK3) [MIM:607654]: A dermatological disorder characterized by thickening of the stratum corneum and epidermal layers on palms and soles. There is no involvement of non-palmoplantar skin, and both hair and nails are normal. {ECO:0000269 PubMed:11982762}. Note=The disease is caused by mutations affecting the gene represented in this entry.
