4-Thio Uridine is typically used to modify oligos slated for RNA, or RNA-protein, structural studies. A 4-thio-rU modified RNA pentamer was used to study the effect of this modification on codon-anticodon interaction when it is in the wobble position of tRNA. Because 4-thio-rU is photoreactive, 4-thio-rU modified RNA oligos have also been used as photoaffinity probes in the role of substrate analogs for characterizing the enzyme:substrate complex of tRNA:pseudouridine-5S synthase . 4-thio-rU modified oligos have also been used as modules for assembling U25 small nucleolar RNAs (U25snoRNA) by ligation. These snoRNAs were used in cross-linking studies to identify which proteins assembled on them in vivo in Xenopus oocytes. In addition, because the thiol group is chemically reactive, other moieties can be conjugated at the thiol group of 4-thio-rU. Such a strategy was used to introduce spin labels to 4-thio-rU-containing RNA oligos.
