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 (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with hair keratins. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the KRTAP type 3 family.
