CC   -!- FUNCTION: Type I keratin involved in the formation and maintenance of
CC       various skin appendages, specifically in determining shape and
CC       orientation of hair (PubMed:14714564, PubMed:16702408). Required for
CC       the correct growth of hair follicles, in particular for the persistence
CC       of the anagen (growth) state (PubMed:16702408). Modulates the function
CC       of TNF-alpha in the specific context of hair cycling. Regulates protein
CC       synthesis and epithelial cell growth through binding to the adapter
CC       protein SFN and by stimulating Akt/mTOR pathway (PubMed:16710422).
CC       Involved in tissue repair. May be a marker of basal cell
CC       differentiation in complex epithelia and therefore indicative of a
CC       certain type of epithelial 'stem cells'. Acts as a promoter of
CC       epithelial proliferation by acting a regulator of immune response in
CC       skin: promotes Th1/Th17-dominated immune environment contributing to
CC       the development of basaloid skin tumors (PubMed:20871598). May act as
CC       an autoantigen in the immunopathogenesis of psoriasis, with certain
CC       peptide regions being a major target for autoreactive T-cells and hence
CC       causing their proliferation. {ECO:0000269|PubMed:14714564,
CC       ECO:0000269|PubMed:16702408, ECO:0000269|PubMed:16710422,
CC       ECO:0000269|PubMed:20871598, ECO:0000269|PubMed:9786956}.
CC   -!- SUBUNIT: Heterodimer of a type I and a type II keratin. KRT17
CC       associates with KRT6 isomers (KRT6A or KRT6B) (By similarity).
CC       Interacts with TRADD and SFN. {ECO:0000250,

CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:16702408,
CC       ECO:0000269|PubMed:16710422}.
CC   -!- TISSUE SPECIFICITY: Expressed strongly in outer root sheath and medulla
CC       region of hair follicle and in the early differentiating epithelial
CC       cells (trichocytes) within the hair bulb region. Weak expression in the
CC       matrix cells of hair bulb. Also present in the sweat gland within the
CC       skin, vibrissae follicle, salivary gland, tooth and thymus.
CC       {ECO:0000269|PubMed:10844551, ECO:0000269|PubMed:14714564,
CC       ECO:0000269|PubMed:2433272}.
CC   -!- DEVELOPMENTAL STAGE: Expression first occurs in a subset of epithelial
CC       cells within the single-layered, undifferentiated ectoderm of embryonic
CC       day 10.5 mouse fetuses (PubMed:9786956). In the ensuing 48 hours, K17-
CC       expressing cells give rise to placodes, the precursors of ectoderm-
CC       derived appendages (hair, glands, and tooth), and to periderm
CC       (PubMed:9786956). Expressed in hair follicles and in the basal and
CC       suprabasal layers of the interfollicular epidermis at birth
CC       (PubMed:11408584). {ECO:0000269|PubMed:11408584,
CC       ECO:0000269|PubMed:9786956}.
CC   -!- INDUCTION: Induced in damaged or stressed epidermis and by interferon-
CC       gamma. Up-regulated by LEF1. {ECO:0000269|PubMed:2433272,
CC       ECO:0000269|PubMed:9786956}.
CC   -!- PTM: Phosphorylation at Ser-44 occurs in a growth- and stress-dependent
CC       fashion in skin keratinocytes, it has no effect on filament
CC       organization. {ECO:0000250}.
CC   -!- DISRUPTION PHENOTYPE: Severe alopecia during the first week postbirth,
CC       correlating with hair fragility, alterations in follicular histology,
CC       and apoptosis in matrix cells. {ECO:0000269|PubMed:12050118}.
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.
