The Eps15 homology (EH) module is a protein-protein interaction domain that establishes a network of connections involved in various aspects of endocytosis and sorting. The finding that EH-containing proteins bind to Hrb (a cellular cofactor of the Rev protein) and to the related protein Hrbl raised the possibility that the EH network might also influence(More)
A model has been proposed for the regulation of CD45, and by homology other RPTPs, in which dimerization inhibits phosphatase activity through symmetrical interactions between an inhibitory structural wedge and the catalytic site. Here, we report the phenotype of mice with a single point mutation, glutamate 613 to arginine, that inactivates the inhibitory(More)
Specific binding of HIV-1 viral protein NCp7 to a unique 35-base RNA stem-loop SL1 is critical for formation and packaging of the genomic RNA dimer found within HIV-1 virions. NCp7 binding stimulates refolding of SL1 from a metastable kissing dimer (KD) into thermodynamically stable linear dimer (LD). Using UV melting, gel electrophoresis and heteronuclear(More)
BACKGROUND Xenotropic murine leukemia virus-related virus (XMRV) was recently discovered to be the first human gammaretrovirus that is associated with chronic fatigue syndrome and prostate cancer (PC). Although a mechanism for XMRV carcinogenesis is yet to be established, this virus belongs to the family of gammaretroviruses well known for their ability to(More)
Influenza A viral polymerase is a heterotrimeric complex that consists of PA, PB1, and PB2 subunits. We previously reported that a di-codon substitution mutation (G507A-R508A), denoted J10, in the C-terminal half of PA had no apparent effect on viral RNA synthesis but prevented infectious virus production, indicating that PA may have a novel role(More)
