Steven Clarke has been on the faculty of the UCLA Department of Chemistry and Biochemistry since 1978. He is currently a Distinguished Professor of Biochemistry and Director of the UCLA Cellular and Molecular Biology Training Program. He was born in Los Angeles and attended public schools in Altadena and Pasadena, California. He did his undergraduate work at Pomona College in Claremont, majoring in Chemistry and Zoology. During this time, he did undergraduate research at the UCLA Brain Research Institute with Dr. James E. Skinner and Professor Donald Lindsley on neural mechanisms of attention. He was also an NIH fellow in the laboratory of Dr. Peter Mitchell at Glynn Research Laboratories in Bodmin, England studying mitochondrial amino acid transport. He obtained his PhD in Biochemistry and Molecular Biology at Harvard University working as an NSF Fellow with Professor Guido Guidotti on membrane protein-detergent interactions and the identification of the major rat liver mitochondrial polypeptides as enzymes of the urea cycle. He returned to California to do postdoctoral work as a Miller Fellow at the University of California, Berkeley, with Professor Dan Koshland, identifying membrane receptors for bacterial chemotaxis. His research at UCLA has focused on roles of novel protein methyltransferases in aging and biological regulation highlighted by discoveries of the protein L-isoaspartyl repair methyltransferase, the isoprenylcysteine protein methyltransferase, and the protein phosphatase 2A methyltransferase. He has been a visiting scholar at Princeton University (1986-87), the University of Washington (2004-2005), and Vanderbilt University (2015).
