Protein-coding gene in the species Homo sapiens
Keratin, type I cuticular Ha3-II is a protein that in humans is encoded by the "KRT33B" gene.
The protein encoded by this gene is a member of the keratin gene family. It is one of the type I hair keratin genes which are clustered in a region of chromosome 17q21.2 and have the same direction of transcription. As a type I hair keratin, it is an acidic protein which heterodimerizes with type II hair keratin to form hair and nails. There are two isoforms of this protein, encoded by two separate genes, "KRT33A" and "KRT33B" (this gene).
