WebFeb 8, 2024 · Huntington’s disease is a rare neurodegenerative and autosomal dominant disorder. HD is caused by a mutation in the gene coding for huntingtin (Htt). The result is the production of a mutant Htt with an abnormally long polyglutamine repeat that leads to pathological Htt aggregates. WebMay 12, 2024 · The multiple functions of the wild type Huntington’s disease protein of the sea urchin Hemicentrotus pulcherrimus (Hp-Htt) have been examined using the anti-Hp-Htt antibody (Ab) raised against synthetic oligopeptides.
WebHuntingtin (HTT) is the 3,144–amino acid protein product of the Huntington’s disease gene ( HTT ), which can be traced back through 800 million years of evolution. It carries a trinucleotide CAG repeat that encodes polyglutamine (polyQ) at an evolutionarily conserved NH2-terminal position in exon 1. WebMar 29, 2024 · Huntingtin is a disease gene linked to Huntington's disease, a neurodegenerative disorder characterized by loss of striatal neurons. This is thought to be caused by an expanded, unstable trinucleotide repeat in the huntingtin gene, which translates as a polyglutamine repeat in the protein product.
