Protein Structure
UniProt Annotation
Function Intermediate filament-associated protein that associates in regular arrays with keratin intermediate filaments (KIF) of the inner root sheath cells of the hair follicle and the granular layer of the epidermis. It later becomes cross-linked to KIF by isodipeptide bonds. It may serve as scaffold protein, together with involucrin, in the organization of the cell envelope or even anchor the cell envelope to the KIF network. It may be involved in its own calcium-dependent postsynthetic processing during terminal differentiation.
Subcellular Localization
Disease Associations
Tissue Specificity Found in the hard keratinizing tissues such as the inner root sheath (IRS) of hair follicles and medulla, and in the filiform papillae of dorsal tongue epithelium.
