Abstract:
The article by McConoughey et al in the current issue of EMBO Molecular Medicine examines the contribution of transglutaminase 2 (TG2) to Huntington's disease (HD) pathogenesis. The authors find that TG2 inhibition can ameliorate HD neurodegeneration, and thereby elevate the status of transglutaminases (TGs) to a major therapeutic target-not because of their well-known activity in mutant protein aggregation, but instead based upon their ability to epigenetically modulate transcription and energy production. While the reintroduction of TG inhibition as a therapy for HD may evoke feelings of déjà vu, the outcome this time around could go in a dramatically different direction.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
Translation Produces the Building Blocks of Life
