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.

CC -!- TISSUE SPECIFICITY: Expressed in the hair follicles.
CC {ECO:0000269|PubMed:15955084}.
CC -!- POLYMORPHISM: Numerous size polymorphism are present in KRTAP4 gene
CC family, which are mainly due to variations in the sequence encoding
CC cysteine-rich repeat segments (PubMed:15955084).
CC {ECO:0000269|PubMed:15955084}.
CC -!- SIMILARITY: Belongs to the KRTAP type 4 family. {ECO:0000305}.
