UAP56 is an essential eukaryotic pre-mRNA splicing factor and mRNA export factor. The mechanisms of its functions are not well understood. We determined the crystal structures of the N- and C-terminal domains of human UAP56 (comprising 90% of the full-length UAP56) at 1.9 Å resolution. The two domains each have a RecA-like fold and are connected by a flexible linker. The overall fold of each domain...
Background: Rhinoviruses belong to the picornavirus family and are small, icosahedral, non-enveloped viruses containing one positive RNA strand. Human rhinovirus 16 (HRV16) belongs to the major receptor group of rhinoviruses, for which the cellular receptor is intercellular adhesion molecule-1 (ICAM-1). In many rhinoviruses, one of the viral coat proteins (VP1) contains a hydrophobic pocket which...
Background The over 100 serotypes of human rhinoviruses (HRV) are major causative agents of the common cold in humans. These HRVs can be roughly divided into a major and minor group according to their cellular receptors. They can also be divided into two antiviral groups, A and B, based on their sensitivity to different capsid-binding antiviral compounds. The crystal structures of HRV14 and HRV16,...
