General description

Verrucarin derived from the Myrothecium verrucari, a fungal plant pathogen is a macrocyclic trichothecene compound.


Verrucarin A from Myrothecium sp has been used:
  • as a translation initiation inhibitor in P. falciparum W2 strain
  • as a peptidyl transfer inhibitor to test sensitivity in methyltransferase knock-out S. cerevisiae cells
  • to test its cytotoxicity in renal cell carcinoma cells

Biochem/physiol Actions

Verrucarin A binds to the P and A sites in ribosomes and blocks peptide-bond and translation initiation. It inhibits the clear cell renal cell carcinoma (CCRCC) proliferation. Verrucarin A blocks the peptidyl transferase activity and favors apoptosis induction in cancer cells
Verrucarin A is phytotoxic to plantlet cultures and cytotoxic to cultured mammalian cell lines.

Other Notes

Macrocyclic trichothecene mycotoxin.

Paraspeckles are ribonucleoprotein bodies found in the interchromatin space of mammalian cell nuclei. These structures play a role in regulating the expression of certain genes in differentiated cells by nuclear retention of RNA. The core paraspeckle proteins (PSF/SFPQ, P54NRB/NONO, and...

Signal transduction pathways often use a transcriptional component to mediate adaptive cellular responses. Coactivator proteins function prominently in these pathways as the conduit to the basic transcriptional machinery. Here we present a high-throughput cell-based screening strategy, termed the "coactivator trap,"...
