KRTAP21-3
Description
The KRTAP21-3 (keratin associated protein 21-3) is a protein-coding gene located on chromosome 21.
KRTAP21-3 is a hair keratin-associated protein (KRTAP) that contributes to the formation of a rigid and resistant hair shaft. It is embedded in the interfilamentous matrix of the hair cortex, alongside other KRTAPs and hair keratins. This protein plays a crucial role in the structural integrity of hair through its extensive disulfide bond cross-linking with hair keratins, facilitated by abundant cysteine residues in its structure.
KRTAP21-3 is also known as -.
