CC -!- SUBUNIT: Heterotetramer of two type I and two type II keratins.
CC {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: In skin, only expressed in the suprabasal cells of
CC tail scale epidermis. Suprabasally expressed in stratified squamous
CC epithelia and also in the posterior unit of the complex filiform
CC papillae of tongue. Expressed in rare anatomical sites in which an
CC orthokeratinized stratum corneum would be too soft and a hard
CC keratinized structure would be too rigid to meet the functional
CC requirement of the respective epithelia. {ECO:0000269|PubMed:1385239}.
CC -!- INDUCTION: mRNA synthesis is suppressed during retinoic acid-mediated
CC orthokeratotic conversion of tail scale epidermis.
CC {ECO:0000269|PubMed:1385239}.
CC -!- MISCELLANEOUS: There are two types of hair/microfibrillar keratin, I
CC (acidic) and II (neutral to basic).
CC -!- SIMILARITY: Belongs to the intermediate filament family.
CC {ECO:0000255|PROSITE-ProRule:PRU01188}.
