The novel Parkinson's disease linked mutation G51D attenuates in vitro aggregation and membrane binding of alpha-synuclein, and enhances its secretion and nuclear localization in cells

Respuesta :

PD linked mutation may cause neurodegeneration via different mechanism.

What is Novel Parkinson's disease linked mutation ?

A novel mutation in the α-Synuclein (α-Syn) gene "G51D" was recently identified in two familial cases exhibiting features of Parkinson's disease (PD) and multiple system atrophy (MSA)

  • the G51D mutation significantly attenuates α-Syn aggregation in vitro.

  • it disrupts local helix formation in the presence of SDS, decreases binding to lipid vesicles C-terminal to the site of mutation and severely inhibits helical folding in the presence of acidic vesicles.
