Mechanisms of Gene Expression

 

Lab Photo April 2017

 

We study mechanisms of eukaryotic gene expression, focusing on RNA polymerase II transcription initiation, elongation, and termination, as well as the co-transcriptional processing of mRNA.  We use a wide array of approaches, including classic molecular genetics, genomics, protein biochemistry, mass spectrometry, and single molecule microscopy.  

Current projects include:

  • Coupling of mRNA processing to transcription via phosphorylation of the RNA polymerase II C-terminal domain (CTD)
  • The interplay between transcription and chromatin modifications, especially methylations of histone H3
  • The role of overlapping non-coding RNA transcription in modifying mRNA expression
  • The proteomics of transcription initiation and elongation (in collaboration with Jarrod Marto, DFCI/HMS)
  • Single molecule studies of RNA polymerase II transcription (in collaboration with Jeff Gelles, Brandeis University)
