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. Required for the correct growth of hair follicles,
CC in particular for the persistence of the anagen (growth) state.
CC Modulates the function of TNF-alpha in the specific context of hair
CC cycling. Regulates protein synthesis and epithelial cell growth through
CC binding to the adapter protein SFN and by stimulating Akt/mTOR pathway.
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. May act as an autoantigen in
CC the immunopathogenesis of psoriasis, with certain peptide regions being
CC a major target for autoreactive T-cells and hence causing their
CC proliferation. {ECO:0000250|UniProtKB:Q04695,
CC ECO:0000250|UniProtKB:Q9QWL7}.
CC -!- SUBUNIT: Heterodimer of a type I and a type II keratin. KRT17
CC associates with KRT6 isomers (KRT6A or KRT6B). Interacts with TRADD and
CC SFN (By similarity). {ECO:0000250|UniProtKB:Q9QWL7, ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9QWL7}.
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 -!- 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 {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the intermediate filament family.
CC {ECO:0000255|PROSITE-ProRule:PRU01188}.
