Assembly of Viral Membrane Proteins.
The generation of computational models is an alternative route to obtain reliable structures for the oligomeric state of membrane proteins. A strategy has been developed to search the conformational space of all possible assemblies in a reasonable time, taking symmetry considerations into account. The methodology tested on M2 from influenza A, shows an excellent agreement with established struc...
متن کاملIFITM Proteins Restrict Viral Membrane Hemifusion
The interferon-inducible transmembrane (IFITM) protein family represents a new class of cellular restriction factors that block early stages of viral replication; the underlying mechanism is currently not known. Here we provide evidence that IFITM proteins restrict membrane fusion induced by representatives of all three classes of viral membrane fusion proteins. IFITM1 profoundly suppressed syn...
متن کاملInteraction of viral oncogenic proteins with the Wnt signaling pathway
It is estimated that up to 20% of all types of human cancers worldwide are attributed to viruses. The genome of oncogenic viruses carries genes that have protein products that act as oncoproteins in cell proliferation and transformation. The modulation of cell cycle control mechanisms, cellular regulatory and signaling pathways by oncogenic viruses, plays an important role in viral carcinogenes...
متن کاملAssembly and Stability of α-Helical Membrane Proteins.
Grease to grease - this is how one might begin to describe the tendency of hydrophobic stretches in protein amino acid sequences to form transmembrane domains. While this simple rule contains a lot of truth, the mechanisms of membrane protein folding, the insertion of hydrophobic protein domains into the lipid bilayer, and the apparent existence of highly polar residues in some proteins in the ...
متن کاملStructure and Assembly of β-Barrel Membrane Proteins
Integral membrane proteins fall into two major structural classes; they consist of individual or bundled TM -helices, or they form monomeric, dimeric, or trimeric TM -barrels. These folds are dictated by the necessity to form oriented hydrogenbonded secondary structures in the highly ordered apolar environment of the lipid bilayer. No other structural motif has yet been confirmed for membrane p...
