The human exosome: an autoantigenic complex of exoribonucleases in myositis and scleroderma [PDF]
Arthritis Research & Therapy, 2000 The anti-PM/Scl autoantibodies are known to characterize a subset of autoimmune patients with myositis, scleroderma (Scl), and the PM/Scl overlap syndrome. The major autoantigens that are recognized by anti-PM/Scl autoantibodies are designated PM/Scl-100 and PM/Scl-75.

The structure of Rph, an exoribonuclease from Bacillus anthracis, at 1.7 angstrom resolution [PDF]
, 2008 Maturation of tRNA precursors into functional tRNA molecules requires trimming of the primary transcript at both the 5' and 3' ends. Cleavage of nucleotides from the 3' stem of tRNA precursors, releasing nucleotide diphosphates, is accomplished in ...

Characterization of a bafinivirus exoribonuclease activity
Journal of General Virology, 2018 White bream virus (WBV), a poorly characterized plus-strand RNA virus infecting freshwater fish of the Cyprinidae family, is the prototype species of the genus Bafinivirus in the subfamily Torovirinae (family Coronaviridae, order Nidovirales). In common with other nidoviruses featuring >20 kilobase genomes, bafiniviruses have been predicted to encode ...

Suppression of Viral RNA Recombination by a Host Exoribonuclease [PDF]
Journal of Virology, 2006 ABSTRACT RNA viruses of humans, animals, and plants evolve rapidly due to mutations and RNA recombination. A previous genome-wide screen in Saccharomyces cerevisiae , a model host, identified five host genes, including XRN1 , encoding a 5′-3′ exoribonuclease, whose absence led to an
