Target Background

Histone demethylase that specifically demethylates both mono- and dimethylated 'Lys-9' of histone H3. May act as a transcription regulator controlling hair biology (via targeting of collagens), neural activity, and cell cycle.

  8. we have identified a mutation, c.74C>T, in a Chinese family with MUHH, which has been previously described in a family from Hungary. Our findings therefore indicate the prevalence of this mutation in diverse populations. PMID: 24261346
  9. Findings indicate that hairless (HR) is a H3K9 demethylase that regulates epidermal homeostasis via direct control of its target genes. PMID: 24334705
  10. Unliganded VDR upregulates the expression of hairless, the gene product of which acts as a downstream comodulator to feedback-repress DKKL1 and SOSTDC1. PMID: 24190897
  11. novel heterozygous mutation in the first Japanese case of Marie Unna hereditary hypotrichosis PMID: 23293922
  12. data demonstrates an acceleration of HR sequence evolution in human branch and suggests that the ability of HR protein to mediate postnatal hair-cycling has been altered in the course of human evolution. PMID: 22355551
  13. We have identified a novel heterozygous missense mutation in a Chinese patient with Marie Unna hereditary hypotrichosis. PMID: 22155146
  14. deletion mutants of hairless indicate that the JmjC domain contributes to the co-repressor activity PMID: 21982945
  15. DNA sequence analysis of the HR gene revealed three novel mutations including two nonsense (p.Cys690X, p.Arg819X) and a missense (p.Pro1157Arg) in four families with congenital atrichia with papular lesions. PMID: 21919222
  16. The index patient displayed the typical pattern of hair loss and was found to carry the disease-causing c.3G>A (p.M1I) U2HR mutation PMID: 20659777
  17. Mutations in the gene HR coding for the hairless protein are associated with an autosomal recessive form of alopecia universalis PMID: 21272494
  18. Marie Unna hereditary hypotrichosis is caused by a novel mutation (U2HR) in the human hairless transcript. PMID: 20163456
  19. study reports a family with Marie Unna hereditary hypotrichosis (MUHH) from Turkey; identified the mutation c.2T > C (M1T) in all affected family members; concluded that there may be considerable clinical variations in MUHH PMID: 20814945
  20. the first time that a mutation in U2HR has been identified in families from the Middle East PMID: 20055871
  21. Hr and VDR interact via multiple protein-protein interfaces, catalyzing histone demethylation to effect chromatin remodeling and repress the transcription of VDR target genes that control the hair cycle. PMID: 20512927

  29. all of the pathogenic HR mutants bound VDR but exhibited reduced binding to histone deacetylase 1 (HDAC1), suggesting that the impaired corepressor activity is due in part to defective interactions with HDACs PMID: 17609203
