Protein attributes
| Sequence length | 403 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Involved in the organization of myofibers. Together with KRT8, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle By similarity. |
| Subunit structure | Heterotetramer of two type I and two type II keratins. Interacts with PNN By similarity. Interacts with the actin-binding domain of DMD. Ref.1 |
| Tissue specificity | Expressed in brain, heart, skin and in costameres of myoplasm at the sarcolemmal membrane in skeletal and cardiac muscle fibers. Undifferentiated gonads and somatic cells of ovarian cords throughout the fetal ovary development. Ref.1 Ref.5 |
| Developmental stage | Found in somatic cells of ovarian cords throughout the fetal ovary development. Ref.5 |
| Domain | This keratin differs from all other IF proteins in lacking the C-terminal tail domain. |
| Miscellaneous | There are two types of cytoskeletal and microfibrillar keratin: I (acidic; 40-55 kDa) and II (neutral to basic; 56-70 kDa). |
| Sequence similarities | Belongs to the intermediate filament family. |
| Sequence caution | The sequence AAH88424.1 differs from that shown. Reason: Erroneous initiation. |
