Journal ArticleDOI
Altered calcium homeostasis in autism-spectrum disorders: Evidence from biochemical and genetic studies of the mitochondrial aspartate/glutamate carrier AGC1
Luigi Palmieri,V. Papaleo,Vito Porcelli,Pasquale Scarcia,L. Gaita,Roberto Sacco,Jörg Hager,Francis Rousseau,Paolo Curatolo,Barbara Manzi,Roberto Militerni,Carmela Bravaccio,Simona Trillo,Cindy Schneider,Raun Melmed,Maurizio Elia,C. Lenti,Monica Saccani,Tiziana Pascucci,Stefano Puglisi-Allegra,Karl L. Reichelt,Antonio M. Persico +21 more
TL;DR: Excessive Ca2+ levels are responsible for boosting AGC activity, mitochondrial metabolism and, to a more variable degree, oxidative stress in autistic brains, and their modulation could provide new preventive and therapeutic strategies.
Journal ArticleDOI
Computational approaches for protein function prediction: A combined strategy from multiple sequence alignment to molecular docking-based virtual screening
TL;DR: In this review the state-of-the-art of computational approaches in 3D protein comparative modeling and in the study of protein-ligand interactions is provided and a possible combined/concerted multistep strategy for protein function prediction is described.
Journal ArticleDOI
Acetylation of human mitochondrial citrate carrier modulates mitochondrial citrate/malate exchange activity to sustain NADPH production during macrophage activation
Erika M. Palmieri,Iolanda Spera,Alessio Menga,Vittoria Infantino,Vito Porcelli,Vito Iacobazzi,Ciro Leonardo Pierri,Douglas C. Hooper,Ferdinando Palmieri,Alessandra Castegna +9 more
TL;DR: It is demonstrated that, in the absence of glucose, activated macrophages increase CIC acetylation to enhance citrate efflux from mitochondria not only to produce inflammatory mediators but also to meet the NADPH demand through the actions of isocitrate dehydrogenase and malic enzyme.
Journal ArticleDOI
The human gene SLC25A29, of solute carrier family 25, encodes a mitochondrial transporter of basic amino acids.
TL;DR: This carrier catalyzed substantial uniport besides a counter-exchange transport, exhibited a high transport affinity for arginine and lysine, and was saturable and inhibited by mercurial compounds and other inhibitors of mitochondrial carriers to various degrees.
Journal ArticleDOI
Mutations in the Mitochondrial Citrate Carrier SLC25A1 are Associated with Impaired Neuromuscular Transmission.
Amina Chaouch,Vito Porcelli,Dan Cox,Shimon Edvardson,Pasquale Scarcia,Anna De Grassi,Ciro Leonardo Pierri,Judith Cossins,Steven H. Laval,Helen Griffin,Juliane S. Müller,Teresinha Evangelista,Ana Töpf,Angela Abicht,Angela Huebner,Maja von der Hagen,Kate Bushby,Volker Straub,Rita Horvath,Orly Elpeleg,Jacqueline Palace,Jan Senderek,David Beeson,Luigi Palmieri,Hanns Lochmüller +24 more
TL;DR: It is hypothesized that the neuromuscular junction impairment may be related to pre-synaptic nerve terminal abnormalities, and the findings highlight the complex machinery required to ensure efficient neuromUScular function, beyond the proteomes exclusive to the neurmuscular synapse.
