CC -!- FUNCTION: Involved in the organization of myofibers. Together with
CC KRT8, helps to link the contractile apparatus to dystrophin at the
CC costameres of striated muscle (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Heterotetramer of two type I and two type II keratins.
CC Interacts with PNN (By similarity). Interacts with the actin-binding
CC domain of DMD. {ECO:0000250, ECO:0000269|PubMed:15247274}.
CC -!- INTERACTION:
CC Q63279; P11530: Dmd; NbExp=3; IntAct=EBI-876985, EBI-706166;
CC -!- TISSUE SPECIFICITY: Expressed in brain, heart, skin and in costameres
CC of myoplasm at the sarcolemmal membrane in skeletal and cardiac muscle
CC fibers. Undifferentiated gonads and somatic cells of ovarian cords
CC throughout the fetal ovary development. {ECO:0000269|PubMed:15247274,
CC ECO:0000269|PubMed:8541209}.
CC -!- DEVELOPMENTAL STAGE: Found in somatic cells of ovarian cords throughout
CC the fetal ovary development. {ECO:0000269|PubMed:8541209}.
CC -!- DOMAIN: This keratin differs from all other IF proteins in lacking the
CC C-terminal tail domain.
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}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAH88424.1; Type=Erroneous initiation; Evidence={ECO:0000305};
