Generic protein structure example

HR is a gene encoding Protein hairless.[1][2][3]

This gene encodes a protein whose function has been linked to hair growth. A similar protein in rat functions as a transcriptional corepressor for thyroid hormone and interacts with histone deacetylases.[3]

Human Genetics

Variations in this gene are involved in low levels of hair (baldness / alopecia / hypotrichosis)[4] Mutations in this gene in humans have been documented in cases of autosomal recessive congenital alopecia[5] and atrichia with papular lesions.[6][7] [8] [9] [10]

The protein contains a Zinc finger domain.[8][6]
