General annotation (Comments)

Subunit structure

Heterotetramer of two type I and two type II keratins. Keratin-5 associates with keratin-14. Interacts with TCHP By similarity. UniProtKB P13647

Tissue specificity

Expressed in epidermis. Ref.1

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.
