Researchers determine architecture of a macromolecular complex regulating gene expression and DNA repair

General transcription factor TFIIH plays central roles in gene transcription and DNA repair ISB researchers and collaborators map the architecture of the TFIIH complex using powerful crosslinking-mass spectrometry (CXMS) technology and integrative modeling Structural maps provide critical insights into how mutations in TFIIH subunits lead to disease phenotypes By Jie Luo and Mark Gillespie The expression, or transcription, of genes controls the identity and function of a cell. DNA damage…

New Structural Map Helps To Understand Aggressive Tumors

3 Bullets: Aggressive tumor growth is linked to high activity of a macromolecular assembly called RNA polymerase I. ISB and FHCRC researchers collaborate to map the architecture of the assembly using a powerful crosslinking-mass spectrometry (CXMS) technology. Structural maps provide important insights into therapeutic targets for cancer treatment. By Mark Gillespie Rapidly growing tumor cells require large amounts of protein for their survival. This increased protein synthesis, or translation, can…
