Michele Pagano is an Italian-American biochemist and cancer biologist best known for his work on cell cycle control and the ubiquitin-proteasome system. He is currently the chairman of the Department of Biochemistry and Molecular Pharmacology, and the Ellen and Gerald Ritter Professor of Oncology at the New York University School of Medicine. He is also an Investigator of the Howard Hughes Medical Institute. His laboratory has played a central role in elucidating the role of a family of enzymes, the cullin-RING ubiquitin ligases (CRLs), in mediating the proteolysis of key cellular regulators. In particular, his work has uncovered the molecular mechanisms by which CRLs control cell cycle progression, signal transduction pathways, and the DNA damage response. His work has also elucidated how
