General annotation (Comments)

Function

May serve an important special function either in the mature palmar and plantar skin tissue or in the morphogenetic program of the formation of these tissues. Plays a role in keratin filament assembly By similarity. Plays an essential role in the correct development of sperm. Ref.1 UniProtKB P35527

Subunit structure

Heterotetramer of two type I and two type II keratins.

Tissue specificity

Expressed in footpad epidermis and testis (at protein level). Ref.1

Miscellaneous

There are two types of cytoskeletal and microfibrillar keratin, I (acidic) and II (neutral to basic) (40-55 and 56-70 kDa, respectively).

Sequence similarities

Belongs to the intermediate filament family.
