Distinct roles of the N-terminal-binding domain and the C-terminal-solubilizing domain of alpha-synuclein, a molecular chaperone.
alpha-Synuclein, an acidic neuronal protein of 140 amino acids, is extremely heat-resistant and is natively unfolded. Recent studies have demonstrated that alpha-synuclein has chaperone activity both in vitro and in vivo, and that this activity is lost upon removing its C-terminal acidic tail. However, the detailed mechanism of the chaperone action of alpha-synuclein remains unknown. In this st...
متن کاملCalcium(II) selectively induces alpha-synuclein annular oligomers via interaction with the C-terminal domain.
Alpha-synuclein filaments are the major component of intracytoplasmic inclusion bodies characteristic of Parkinson's disease and related disorders. The process of alpha-synuclein filament formation proceeds via intermediate or protofibrillar species, each of which may be cytotoxic. Because high levels of calcium(II) and other metal ions may play a role in disease pathogenesis, we investigated t...
متن کاملThe role of the C-terminal tail of flavocytochrome b2.
A flavocytochrome b2 (L-lactate dehydrogenase) mutant was constructed in which the C-terminal tail (23 amino acid residues) had been deleted (Gly-489----Stop). This tail appears to form many intersubunit contacts in the tetrameric wild-type protein, and it was expected that its removal might lead to the formation of monomeric flavocytochrome b2. The isolated tail-deleted mutant enzyme (TD-b2), ...
متن کاملOligomerization of the cardiac ryanodine receptor C-terminal tail.
The C-terminal 100 amino acids of the RyR (ryanodine receptor), referred to as the C-terminal tail, is a highly conserved sequence that is present in all known RyR isoforms and which has been implicated in channel function. Deleting the final 15 amino acids from the full-length skeletal muscle RyR resulted in an inactive channel, attributed to impaired assembly of a tetrameric RyR complex [Gao,...
متن کاملMultifunctional role of the Pitx2 homeodomain protein C-terminal tail.
Pitx2 is a newly described bicoid-like homeodomain transcription factor that is defective in Rieger syndrome and shows a striking leftward developmental asymmetry. We have previously shown that Pitx2 (also called Ptx2 and RIEG) transactivates a reporter gene containing a bicoid enhancer and synergistically transactivates the prolactin promoter in the presence of the POU homeodomain protein Pit-...
