function:In the hair cortex, hair keratin intermediate filaments are embedded in an interfilamentous matrix, consisting of hair keratin-associated proteins (KRTAP), which are essential for the formation of a rigid and resistant hair shaft through their extensive disulfide bond cross-linking with abundant cysteine residues of hair keratins. The matrix proteins include the high-sulfur and high-glycine-tyrosine keratins.,similarity:Belongs to the KRTAP type 8 family.,subunit:Interacts with hair keratins.,tissue specificity:Is essentially restricted to only one vertical half of the hair forming compartment and in beard hairs is absent from the central medulla.,
