| pubmed-article:16911959 | pubmed:abstractText | The tetrameric protein transthyretin (TTR) forms amyloid fibrils upon dissociation and subsequent monomer misfolding, enabling misassembly. Remarkably, the aggregation of one of over 100 destabilized TTR variants leads to familial amyloid disease. It is known that trans-suppression mediated by the incorporation of T119M subunits into tetramers otherwise composed of the most common familial variant V30M, ameliorates disease by substantially slowing the rate of tetramer dissociation, a mechanism referred to as kinetic stabilization of the native state. R104H TTR has been reported to be non-pathogenic, and recently, this variant has been invoked as a trans-suppressor of amyloid fibril formation. Here, we demonstrate that the trans-suppression mechanism of R104H does not involve kinetic stabilization of the tetrameric structure, instead its modest trans-suppression most likely results from the thermodynamic stabilization of the tetrameric TTR structure. Thermodynamic stabilization increases the fraction of tetramer at the expense of the misfolding competent monomer decreasing the ability of TTR to aggregate into amyloid fibrils. As a consequence of this stabilization mechanism, R104H may be capable of protecting patients with modestly destabilizing mutations against amyloidosis by slightly lowering the overall population of monomeric protein that can misfold and form amyloid. | lld:pubmed |
