Keratin (Wool-derived) (KRT)

Wool protein primarily consists of alpha-keratins, which are intermediate filament proteins that provide structural integrity to the wool fiber (UniProt). These proteins are characterized by a high cysteine content, facilitating disulfide bridge formation which contributes to the mechanical durability and chemical resistance of the material (PubMed, PMID: 28814646). While not a conventional therapeutic target for drug development, wool-derived keratin is extensively researched as a biomaterial for wound healing and tissue engineering due to its biocompatibility and ability to support cellular adhesion and proliferation (PubMed, PMID: 30173112). In clinical practice, wool proteins and associated substances like lanolin are more frequently recognized as contact allergens or irritants rather than targets for pharmacological modulation (StatPearls). Consequently, wool protein is considered an incorrect designation for a therapeutic target, as it describes a structural material rather than a specific drug-regulatable biological entity.
