[Abstract]  The RNA exosome complex plays a central role in RNA processing and regulated turnover. Present both in cytoplasm and nucleus, the exosome functions through associations with ribonucleases and various adapter proteins (reviewed in [Kilchert et al., 2016]). The following protocol describes an approach to purify RNA exosome complexes from HEK-293 cells, making use of inducible ectopic expression, affinity capture, and rate-zonal centrifugation. The obtained RNA exosomes have been used ...

[Abstract]  Respiratory syncytial virus (RSV) belongs to the paramyxovirus family that includes many clinically relevant viruses, such as the human metapneumovirus and measles. RSV infection can cause severe disease in infants, the elderly, and some immunocompromised adults. During RSV replication, a series of truncated forms of the viral genome is generated. These truncated viral genomes are known as defective viral genomes (DVGs) and are generated by many viruses (Lazzarini et al., ...

Purification of 70S Ribosomes from Bacillus subtilis

[Abstract]  The eubacterial ribosome (70S) is a macromolecular complex that is composed of a small (30S) subunit and a large (50S) subunit. The small subunit comprises the 16S ribosomal RNA (rRNA) and more than 20 ribosomal proteins (r-proteins), whereas the large subunit comprises the 23S and 5S rRNAs and more than 30 r-proteins. Bacillus subtilis (B. subtilis) has 57 r-ribosomal protein genes and three rRNAs (16S, 23S and 5S rRNAs). Among them, we identified 21 r-proteins of the small ...
