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