For discovering the human origin recognition complex and pre-replication complex proteins responsible for orchestrating DNA replication, and for further elucidating the mechanisms by which DNA and chromatin are effectively replicated, defining how genetic material is transferred, and how aberrations in replication may contribute to cancer.

Internationally heralded, Dr. Stillman is recognized for his seminal contributions to the understanding of eukaryotic DNA replication, including the discovery of the human origin recognition complex (ORC) and pre-replication complex (pre-RC) proteins responsible for orchestrating replication. His research has explained the mechanisms by which DNA is replicated, demonstrating how genetic material is transferred and how aberrations in this process may contribute to cancer. His research endeavors included studying SV40 viral replication, resulting in fundamental discoveries that culminated in the complete biochemical reconstitution of SV40 DNA replication. This work delineated the factors required at the replication fork, including replication protein A, replication factor C, proliferating cell nuclear antigen and DNA polymerase-δ and a chromatin assembly protein CAF-1, a protein complex required for the assembly of histone tetramers onto replicated DNA molecules.

During cell division, the genome replication process must be tightly regulated to occur only once during cell division. In a landmark publication, Dr. Stillman used yeast as a model system to identify the six subunits of the ORC (ORC1-6) that recognizes the cellular origins of DNA replication in an ATP-dependent manner. Dr. Stillman also contributed to the identification of the pre-replication complex (pre-RC), composed of the ORC, MCM proteins, Cdc6 and Cdt1. In addition, he has elucidated additional roles that ORC proteins play in human cells, including control of centrosome duplication and gene silencing by in cooperation with the Retinoblastoma tumor suppressor protein, highlighting how ORC ensures successful mammalian cell division. More recently, his research group and collaborators contributed to the visualization at atomic resolution of the ORC, Cdc6, Cdt1 and Mcm2-7 proteins bound to DNA by using cryo-electron microscopy. This work has shed light on the impact of human ORC mutations, found in patients with Meier-Gorlin Syndrome, on ATP-dependent activities with consequences that extend to other illnesses including cancer.
