CC   -!- FUNCTION: In the hair cortex, hair keratin intermediate filaments
CC       are embedded in an interfilamentous matrix, consisting of hair
CC       keratin-associated protein (KRTAP), which are essential for the
CC       formation of a rigid and resistant hair shaft through their
CC       extensive disulfide bond cross-linking with abundant cysteine
CC       residues of hair keratins. The matrix proteins include the high-
CC       sulfur and high-glycine-tyrosine keratins.
CC   -!- SUBUNIT: Interacts with hair keratins.
