Previously Unknown Protein Reveals RNA Repair Mechanism in Humans

Ribonucleic acids (RNAs) are single-stranded molecules that are found in all living organisms’ cells. As “transcripts” of human genes, mRNAs, for instance, play a role in the translation of genetic information by bearing the instructions for the production of a protein in their own sequence.

Highly sensitive bioluminescent platform for nucleic acid detection

Despite significant advances, numerous highly sensitive viral disease diagnostic tests even now require complex techniques to prepare a sample or decipher a result, making them inconvenient for point-of-care settings or areas with limited resources.

Study reveals why the FMO5 gene produces an enzyme with a different activity

Our body produces lots of enzymes that break down toxic substances. One class of such enzymes are the flavin-containing monooxygenases (FMOs), which are present in all tetrapods. Humans have five different FMO genes, of which the first four display the same activity. However, the fifth FMO gene triggers a different breakdown reaction. University of Groningen biochemists have succeeded in resurrecting the ancestral genes of all tetrapod FMOs to show how this divergence has occurred. Their results appear on 24 February in Nature Communications.
