HR (hairless) is 1189 amino acids long, weighing approximately 127 kDa, with a short isomer that is 1134 amino acids long, weighing approximately 122 kDa. HR functions as a transcription factor that regulates the phases of hair growth, with strong expressions in the small intestine and the skin (for isoform 2 only), and weak expressions in the brain and colon. Current studies are being done on several diseases and disorders including atrichia with popular lesions, hypotrichosis, thyroiditis, and autosomal recessive diseases. HR has also been shown to have interactions with VDR, ESR2, RARA, TBL1X, and HDAC1.
