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

Mitochondria are eukaryotic organelles that generate most of the energy in the cell by oxidative phosphorylation (OXPHOS). Each mitochondrion contains multiple copies of a closed circular double-stranded DNA genome (mtDNA). Human (mammalian) mtDNA encodes 13 essential subunits of the inner

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

DNA damage activates TP53-regulated surveillance mechanisms that are crucial in suppressing tumorigenesis. TP53 orchestrates these responses directly by transcriptionally modulating genes, including microRNAs (miRNAs), and by regulating miRNA biogenesis through interacting with the DROSHA complex. However, whether the association between
