Keratin, type I cuticular Ha1 is a protein that in humans is encoded by the KRT31 gene.^[5]^[6]^[7]

Function

The protein encoded by this gene is a member of the keratin gene family. As a type I hair keratin, it is an acidic protein which heterodimerizes with type II keratins to form hair and nails. The type I hair keratins are clustered in a region of chromosome 17q12-q21 and have the same direction of transcription.^[7]
