KRTAP9-3
Description
The KRTAP9-3 (keratin associated protein 9-3) is a protein-coding gene located on chromosome 17.
KRTAP9-3 is a key component of the hair shaft's interfilamentous matrix, a network of proteins that surrounds and supports the keratin filaments. This matrix is crucial for the strength and resilience of hair, as KRTAP9-3's abundant cysteine residues form extensive disulfide bonds with hair keratins, effectively cross-linking them together. This process contributes significantly to the rigidity and resistance of the hair shaft.
KRTAP9-3 is also known as KAP9.3, KRTAP9.3.
