Salmonella Engages Host MicroRNAs To Modulate SUMOylation: a New Arsenal for Intracellular Survival.

abstract：:A novel small nuclear ribonucleoprotein (snRNP) complex containing both U11 and U12 RNAs has been identified in HeLa cell extracts. This U11/U12 snRNP complex can be visualized on glycerol gradients, on native polyacrylamide gels, and by selection with antisense 2'-O-methyl oligoribonucleotides. RNase H-mediated degra...
