Neurotoxin-induced selective ubiquitination and regulation of MEF2A isoform in neuronal stress response.

abstract：:The physiological function of the cellular prion protein (PrP(c)) is unclear. PrP(c) associates with lipid rafts, highly glycolipid-rich membrane domains containing a large variety of signaling molecules, e.g., sphingolipids (SL). In this study, we investigated possible connections between PrP(c) and sphingolipid-asso...
