General description

4-Thiouridine is a photoreactive uridine analog.

Application

4-Thiouridine has been used in labeling and isolation of nascent RNAs.

Biochem/physiol Actions

4-Thiouridine plays a role in assessing nascent RNA synthesis. It also enhances site-specific crosslinking. 4-Thiouridine also acts as a photoaffinity probe due to its stability even while lacking specific photoactivation. It can also be incorporated into RNAs.

Storage Class

11 - Combustible Solids

In eukaryotes, the synthesis of ribosomal subunits, which involves the maturation of the ribosomal (r)RNAs and assembly of ribosomal proteins, requires the co-ordinated action of a plethora of ribosome biogenesis factors. Many of these cofactors remain to be characterized in
