Hairless Rabbit Polyclonal Antibody

This gene encodes a protein that is involved in hair growth. This protein functions as a transcriptional corepressor of multiple nuclear receptors, including thyroid hormone receptor, the retinoic acid receptor-related orphan receptors and the vitamin D receptors, and it interacts with histone deacetylases. The translation of this protein is modulated by a regulatory open reading frame (ORF) that exists upstream of the primary ORF. Mutations in this upstream ORF cause Marie Unna hereditary hypotrichosis (MUHH), an autosomal dominant form of genetic hair loss. Mutations in this gene also cause autosomal recessive congenital alopecia and atrichia with papular lesions, other diseases resulting in hair loss. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2014], alternative products:Additional isoforms seem to exist, disease:Defects in HR are the cause of alopecia universalis congenita (ALUNC) [MIM:203655]. ALUNC is a rare autosomal recessive form of hair loss characterized by hair follicles without hair., disease:Defects in HR are the cause of atrichia with papular lesions (APL) [MIM:209500]; also known as congenital atrichia. APL is an autosomal recessive disease characterized by papillary lesions over most of the body and almost complete absence of hair., function:May act as a transcription factor that could act on to regulate one of the phases of hair growth., similarity:Contains 1 JmjC domain., tissue specificity:Strongest expression of isoforms 1 and 2 is seen in the small intestine, weaker expression in brain and colon, and trace expression is found in liver, pancreas, spleen, thymus, stomach, salivary gland, appendix and trachea. Isoform 1 is always the most abundant. Isoform 1 is exclusively expressed at low levels in kidney and testis and isoform 2 exclusively at high levels in the skin.
