Expression:
P02533 K1C14_HUMAN:

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.

P08779 K1C16_HUMAN:

Expressed in the hair follicle, nail bed and in mucosal stratified squamous epithelia and, suprabasally, in oral epithelium and palmoplantar epidermis. Also found in luminal cells of sweat and mammary gland ducts.

Description:
K14 a type I cytoskeletal keratin. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. There are two types of cytoskeletal and microfibrillar keratin: type I (acidic; 40-55 kDa) [K9 to K20] and type II (neutral to basic; 56-70 kDa) [K1 to K8]. Both a basic and an acidic keratin are required for filament assembly. Generally associates with K5. Note: This description may include information from UniProtKB.

Research Backgrounds

Function:

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.

PTMs:

A disulfide bond is formed between rather than within filaments and promotes the formation of a keratin filament cage around the nucleus.

Ubiquitinated by the BCR(KLHL24) E3 ubiquitin ligase complex.

Subcellular Location:

Cytoplasm. Nucleus.
Note: Expressed in both as a filamentous pattern.

Tissue Specificity:

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.

Subunit Structure:

Heterotetramer of two type I and two type II keratins. disulfide-linked keratin-14 associates with keratin-5. Interacts with TRADD and with keratin filaments. Associates with other type I keratins. Interacts with EPPK1 (By similarity). Interacts with KLHL24.

Family&Domains:

Belongs to the intermediate filament family.

Function:

Epidermis-specific type I keratin that plays a key role in skin. Acts as a regulator of innate immunity in response to skin barrier breach: required for some inflammatory checkpoint for the skin barrier maintenance.

Tissue Specificity:

Expressed in the hair follicle, nail bed and in mucosal stratified squamous epithelia and, suprabasally, in oral epithelium and palmoplantar epidermis. Also found in luminal cells of sweat and mammary gland ducts.

Subunit Structure:

Heterodimer of a type I and a type II keratin. KRT16 associates with KRT6 isomers (KRT6A or KRT6B) (By similarity). Interacts with TCHP. Interacts with TRADD (By similarity).

Family&Domains:

Belongs to the intermediate filament family.
