Summaries for KRTAP4-6 Gene

GeneCards Summary for KRTAP4-6 Gene

KRTAP4-6 (Keratin Associated Protein 4-6) is a Protein Coding gene. An important paralog of this gene is KRTAP4-9.

UniProtKB/Swiss-Prot for KRTAP4-6 Gene

  • 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.
