Geoffrey P. Dann, PhD

Dr. Dann is studying how the addition of the amino acid arginine to proteins regulates their biological activity. When this process malfunctions, cancerous genes are transcribed into proteins. Dr. Dann will use high-resolution mass spectrometry to identify arginine-modified proteins in cells, chemical biological tools to decipher the role of such modification in determining protein function, and functional genomics to understand how this process regulates the genome.
