CC -!- FUNCTION: Epidermis-specific type I keratin that plays a key role in
CC skin (PubMed:22336941, PubMed:24218583). Acts as a regulator of innate
CC immunity in response to skin barrier breach: required for some
CC inflammatory checkpoint for the skin barrier maintenance
CC (PubMed:24218583). {ECO:0000269|PubMed:11029038,
CC ECO:0000269|PubMed:22336941, ECO:0000269|PubMed:24218583}.
CC -!- SUBUNIT: Heterodimer of a type I and a type II keratin. KRT16
CC associates with KRT6 isomers (KRT6A or KRT6B) (PubMed:8636216).
CC Interacts with TCHP (By similarity). Interacts with TRADD
CC (PubMed:16702408). {ECO:0000250|UniProtKB:P08779,
CC ECO:0000269|PubMed:16702408, ECO:0000269|PubMed:8636216}.
CC -!- TISSUE SPECIFICITY: Expressed in the epithelia of the tongue, upper and
CC lower palate, footpad, proximal nail fold and nail bed, penile spine,
CC sweat gland ducts, and back epidermis (at protein level)
CC (PubMed:12445204). Expressed in upper suprabasal layers of the corneal
CC epithelium (at protein level) (PubMed:26758872). Expressed in internal
CC stratified epithelia in the esophagus and vagina (at protein level)
CC (PubMed:12445204). Expressed in transitional stratified squamous
CC epithelia in the forestomach, anal canal, and nasal cavity (at protein
CC level) (PubMed:12445204). Expressed in transitional epithelia of the
CC ureter, bladder and urethra (at protein level) (PubMed:12445204). In
CC mature hair follicles, expressed in the companion layer of the outer
CC root sheath during anagen and in the club hair sheath during catagen
CC and telogen (at protein level) (PubMed:12445204).
CC {ECO:0000269|PubMed:12445204, ECO:0000269|PubMed:26758872}.
CC -!- DEVELOPMENTAL STAGE: During embryonic development, initially localizes
CC within early hair germs, but rapidly shifts to a subset of cells at the
CC interface of basal and suprabasal cells above and around the hair germ
CC (PubMed:12445204). Expressed in hair follicles and in most cells in the
CC spinous layer at birth (PubMed:11408584). {ECO:0000269|PubMed:11408584,
CC ECO:0000269|PubMed:12445204}.
CC -!- INDUCTION: In response to epidermal stress such as wounding.
CC {ECO:0000269|PubMed:8636216}.
CC -!- DISRUPTION PHENOTYPE: Mice were born alive at approximately Mendelian
CC ratios but increased postnatal mortality is observed. Surviving mice
CC show oral lesions as well as palmoplantar keratoderma-like
CC hyperkeratotic calluses on front and hind paws, which impair the
CC ability to walk. {ECO:0000269|PubMed:22336941}.
CC -!- MISCELLANEOUS: There are two types of cytoskeletal and microfibrillar
CC keratin: I (acidic; 40-55 kDa) and II (neutral to basic; 56-70 kDa).
CC -!- SIMILARITY: Belongs to the intermediate filament family.
CC {ECO:0000255|PROSITE-ProRule:PRU01188}.
