Thiolutin has been used as a polymerase II inhibitor:
to study its effects on yeast cells to calculate transcript half-life [1]
to study its effects on transcription during germination in budding yeast [2]
to study its effects on cell adhesion in zebrafish [3]
Biochem/physiol Actions
Sulfur-containing antibiotic, which is a potent inhibitor of bacterial and yeast RNA polymerases. It was found to inhibit in vitro RNA synthesis directed by all three yeast RNA polymerases (I, II, and III). Thiolutin is also an inhibitor of mannan and glucan formation in Saccharomyces cerevisiae and used for the analysis of mRNA stability. Studies have shown that thiolutin inhibits adhesion of human umbilical vein endothelial cells (HUVECs) to vitronectin and thus suppresses tumor cell-induced angiogenesis in vivo.
Preparation Note
Thiolutin dissolves in DMSO at 0.90 - 1.10 mg/ml to yield a clear, yellow solution.

Two mutations in Escherichia coli conferring resistance to the transcription initiation inhibitor, thiolutin, have been mapped. One of these mutations (tln-I)( maps at 10.2 min on the genetic map and is cotransducible with dnaZ at a frequency of approximately 50%.
Thiolutin is commonly used as a general inhibitor of transcription in yeast. It has been used to calculate mRNA decay rates by stopping the transcription and then determining the relative abundance of individual mRNAs at different times after inhibition. We
Nutritional and meiotic induction of transiently heritable stress resistant states in budding yeast
Much of our understanding of eukaryotic mRNA decay has come from studies in budding yeast, Saccharomyces cerevisiae. The facile nature of genetic and biochemical manipulations in yeast has allowed detailed investigations into the mRNA decay pathway and the identification of
The Journal of cell biology, 126(3), 649-659 (1994-08-01)
To understand the mechanisms of mRNA transport in eukaryotes, we have isolated Saccharomyces cerevisiae temperature-sensitive (ts) mutants which accumulate poly(A)+ RNA in the nucleus at the restrictive temperature. A total of 21 recessive mutants were isolated and classified into 16
