Biophysical Aspect of Huntingtin Protein During polyQ: An In Silico Insight.

Huntington's disease (HD) is a neurodegenerative disorder that is caused by an abnormal elongation of the polyglutamine (polyQ) chain in the Huntington (Htt) protein. At present, the normal function of Htt of neurons as well as the mechanism by which selective neurodegeneration is caused by the expanded polyQ chain in Htt remains ambiguous. A gain of function as a result of the elongated polyQ chain can lead to abnormal interaction of the Htt protein with its interacting partners, thereby resulting in the neuropathological changes seen in the Huntington's disease.

Computational investigation of molecular mechanism and neuropathological implications in Huntington disease.

Huntington's disorder (HD), caused by mutations of the IT-15 gene, is an autosomal genetic disease that causes the breakdown of the nerve cells in the brain. The IT-15 gene encodes the huntingtin (Htt) protein. Htt, along with its interacting partners, are involved in maintaining proper communication among neurons.
