NAB 2 is an inhibitor of α-synuclein-induced toxicity. It prevents α-synuclein-induced defects in Rsp5-dependent endocytosis and vacuolar delivery of Mup1, Golgi-to-vacuole trafficking of Sna3, and degradation of Bap2 in wild-type yeast cells. NAB 2 also prevents formation of α-synuclein foci in wild-type yeast cells, an effect that is prevented by the rsp5 point mutation.
NAB2 is a neuroprotectant that targets the small GTPase Rab1a. NAB2 selectively binds to the GDP-bound form of Rab1a and protects multiple cell types from α-synuclein toxicity by increasing Rab1a expression. Rab1a regulates ER-to-Golgi trafficking and mediates endosomal trafficking events of the E3 ubiquitin ligase Rsp5/Nedd4. NAB2 stimulates ubiquitination of related proteins in a Nedd4-dependent manner and rescues α-synuclein-associated trafficking defects associated with early-onset Parkinson's disease.
