title: Role of glutamine deamidation in neurodegenerative diseases associated with triplet repeat expansions: a hypothesis.
abstract: The pathological expansion of unstable trinucleotide repeats is known to cause neurodegenerative diseases. Trinucleotide repeat expansions might prove to be pathological through a variety of mechanisms, including alteration of DNA structure, transcription, RNA-protein interaction, and altered protein conformations/interactions. Deamidation of human proteins have been shown to regulate some time-dependent biological processes such as development and aging. In this paper we hypothesize the possible role of glutamine deamidation as a signaling event in the pathogenesis of neurodegenerative diseases associated with triplet repeat expansion.
