Scientists describe detailed structure and function of the TFIID protein complex

A research team of scientists from EMBL Grenoble and the IGBMC in Strasbourg, France, have, for the first time, described in molecular detail the architecture of the central scaffold of TFIID: the human protein complex essential for transcription from DNA to mRNA. The study, published today in Nature, opens new perspectives in the study of transcription and of the structure and mechanism of other large multi-protein assemblies involved in gene regulation.

TFP5 molecule restores memory in mice with Alzheimer's

A new ray of hope has broken through the clouded outcomes associated with Alzheimer's disease. A new research report published in January 2013 print issue of the FASEB Journal by scientists from the National Institutes of Health shows that when a molecule called TFP5 is injected into mice with disease that is the equivalent of human Alzheimer's, symptoms are reversed and memory is restored-without obvious toxic side effects.
