Multiprotein complexes play central roles in many cellular pathways. Although many high-throughput experimental techniques have already enabled systematic screening of pairwise protein-protein interactions en masse, the amount of experimentally determined protein complex data has remained relatively lacking. As such, researchers have begun to exploit the vast amount of pairwise interaction data...

Recently, it has become evident that nucleolar passage of movement proteins occurs commonly in a number of plant RNA viruses that replicate in the cytoplasm. Systemic movement of Potato mop-top virus (PMTV) involves two viral transport forms represented by a complex of viral RNA and TRIPLE GENE BLOCK1 (TGB1) movement protein and by polar virions that contain the minor coat protein and TGB1 atta...

The nonstructural NSm protein of tomato spotted wilt tospovirus (TSWV) represents a putative viral movement protein involved in cell-to-cell movement of nonenveloped ribonucleocapsid structures. To study the molecular basis of NSm function, we expressed the protein in Escherichia coli and investigated protein-protein and protein-RNA interactions of NSm protein in vitro. NSm specifically interac...

The nonclaret disjunctional (ncd) protein is a kinesin-related microtubule motor protein that is encoded at the claret locus in Drosophila and is required for proper chromosome distribution in meiosis and early mitosis. The protein contains a region with 41% amino acid sequence identity to kinesin heavy chain, but translocates on microtubules with the opposite polarity to kinesin, toward microt...
