CC -!- FUNCTION: May serve an important special function either in the mature
CC palmar and plantar skin tissue or in the morphogenetic program of the
CC formation of these tissues. Plays a role in keratin filament assembly
CC (By similarity). Plays an essential role in the correct development of
CC sperm. {ECO:0000250|UniProtKB:P35527, ECO:0000269|PubMed:16015579}.
CC -!- SUBUNIT: Heterotetramer of two type I and two type II keratins.
CC {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in footpad epidermis and testis (at
CC protein level). {ECO:0000269|PubMed:16015579}.
CC -!- MISCELLANEOUS: There are two types of cytoskeletal and microfibrillar
CC keratin, I (acidic) and II (neutral to basic) (40-55 and 56-70 kDa,
CC respectively). {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the intermediate filament family.
CC {ECO:0000255|PROSITE-ProRule:PRU01188}.
