Function
Structural component of intermediate filaments in basal keratinocytes of stratified epithelia. Forms obligate heteropolymers with the type II keratin KRT5, contributing to the keratin intermediate filament network that confers mechanical strength and structural integrity to the basal layer of the epidermis and other stratified epithelial. The nonhelical tail domain is involved in promoting KRT5-KRT14 filaments to self-organize into large bundles and enhances the mechanical properties involved in resilience of keratin intermediate filaments in vitro.
Biological Context
Subcellular Location: Cytoplasm; Nucleus
Tissue Specificity: Expressed in the corneal epithelium (at protein level). Detected in the basal layer, lowered within the more apically located layers specifically in the stratum spinosum, stratum granulosum but is not detected in stratum corneum. Strongly expressed in the outer root sheath of anagen follicles but not in the germinative matrix, inner root sheath or hair. Found in keratinocytes surrounding the club hair during telogen
Disease Association: Epidermolysis bullosa simplex 1A, generalized severe (EBS1A) : A form of epidermolysis bullosa simplex, a group of skin fragility disorders characterized by skin blistering due to cleavage within the basal layer of keratinocytes, and erosions caused by minor mechanical trauma. There is a broad spectrum of clinical severity ranging from minor blistering on the feet, to subtypes with extracutaneous involvement and a lethal outcome. EBS1A is an autosomal dominant form characterized by generalized intraepidermal skin blistering that begins and is very prominent at birth. EBS1A may be life-threatening in the first year of life. Tendency to blistering diminishes in adolescence.

There is a broad spectrum of clinical severity ranging from minor blistering on the feet, to subtypes with extracutaneous involvement and a lethal outcome. EBS1C is an autosomal dominant form with intraepidermal blistering mainly restricted to hands and feet beginning in infancy. Nails may be thick and dystrophic.

There is a broad spectrum of clinical severity ranging from minor blistering on the feet, to subtypes with extracutaneous involvement and a lethal outcome. EBS1B is an autosomal dominant form characterized by generalized intraepidermal blistering beginning at birth. The tendency to blistering diminishes in adolescence, when it may become localized to hands and feet. [The disease is caused by variants affecting the gene represented in this entry] | Epidermolysis bullosa simplex 1D, generalized, intermediate or severe, autosomal recessive (EBS1D) : A form of epidermolysis bullosa simplex, a group of skin fragility disorders characterized by skin blistering due to cleavage within the basal layer of keratinocytes, and erosions caused by minor mechanical trauma. There is a broad spectrum of clinical severity ranging from minor blistering on the feet, to subtypes with extracutaneous involvement and a lethal outcome. EBS1D is an autosomal recessive form characterized by blistering beginning at birth or early childhood. In some patients hands and feet are primarily affected, and in others blistering anywhere on the body may occur. In some patients the condition improves with age. [The disease is caused by variants affecting the gene represented in this entry] | Naegeli-Franceschetti-Jadassohn syndrome (NFJS) : A rare autosomal dominant form of ectodermal dysplasia. The cardinal features are absence of dermatoglyphics (fingerprints), reticular cutaneous hyperpigmentation (starting at about the age of 2 years without a preceding inflammatory stage), palmoplantar keratoderma, hypohidrosis with diminished sweat gland function and discomfort provoked by heat, nail dystrophy, and tooth enamel defects. [The disease is caused by variants affecting the gene represented in this entry] | Dermatopathia pigmentosa reticularis (DPR) : A rare ectodermal dysplasia characterized by lifelong persistent reticulate hyperpigmentation, non-cicatricial alopecia, and nail dystrophy. Variable features include adermatoglyphia, hypohidrosis or hyperhidrosis, and palmoplantar hyperkeratosis. [The disease is caused by variants affecting the gene represented in this entry]
