KRTAP5 Activators

Keratin Associated Protein 5 (KRTAP5) is a protein in humans that is encoded by the KRTAP5 gene. It is part of the keratin-associated protein (KRTAP) family, a group of proteins that combine with keratin to form hair and nails.Keratins are fibrous structural proteins that constitute the primary structural material of hair, nails, and the outer layer of skin. KRTAPs, including KRTAP5, are small, rich in cysteine proteins that bind to keratin intermediate filaments in hair shafts. They contribute to the formation of a matrix that provides hair with its strength, rigidity, and shape.

Specifically, KRTAP5 is part of the high sulfur KRTAP subgroup, characterized by a high cysteine content. The cysteine residues form disulfide bonds that create a rigid and resistant structure. This structure aids in determining the physical properties of the hair strand, such as its curliness or straightness.In summary, KRTAP5 is a keratin-associated protein that plays a significant role in the formation and physical properties of hair. It binds to keratin intermediate filaments, contributing to the formation of a rigid structure that gives hair its strength and shape. The potential implications of KRTAP5 dysfunction in hair and skin disorders remain an area for future research.
