1.14.11.65 | evolution | the hairless (HR) protein contains a Jumonji C (JmjC) domain that is conserved among a family of proteins with histone demethylase (HDM) activity | Homo sapiens |
1.14.11.65 | malfunction | two missense mutations in gene HR in patients with atrichia with papular lesions abolish the demethylase activity of the enzyme, demonstrating the role of enzyme HR demethylase activity in human disease. Various missense mutations, e.g. mutations D1012N or V1056M, in the HR JmjC domain are associated with atrichia with papular lesions (APL) | Homo sapiens |
