Reid Gilmore, Ph.D.

Oligosaccharyltransferase Mutations: Role in CDG-I

Reid GilmoreProfessor
University of Massachusetts Medical School
Biochemistry and Molecular Pharmacology


Dr. Reid Gilmore received a Ph.D. in Biochemistry from the University of Illinois, Urbana in 1980 for research with Dr. Michael Glaser. Reid's thesis project was to analyze the role of membrane phospholipid composition on the structure and function of the rough endoplasmic reticulum (RER) in mammalian cells. Reid Gilmore conducted his postdoctoral research with Nobel laureate Dr. Gunter Blobel at the Rockefeller University, where he analyzed the mechanism of protein translocation across the RER. In 1985, Reid was appointed as an Associate Professor in the Department of Biochemistry at the University of Massachusetts Medical School (UMMS). At UMMS, Reid continued his research on the mechanism of protein translocation across the ER, and began investigating the oligosaccharyltransferase (OST). The OST is the ER-localized enzyme that transfers a preassembled oligosaccharide onto asparagine residues on newly synthesized proteins in the lumen of the RER. The Gilmore lab has purified the OST from budding yeast and from mammalian pancreatic tissue. The OST is a surprisingly complicated enzyme consisting of seven to eight non-identical subunits. A second layer of complexity is explained by duplication of the catalytic subunit gene to yield alternative catalytic subunits (STT3A or STT3B) that are incorporated into OST isoforms with different in vivo functions. To date, mutations have been identified in at least three OST subunit genes that cause variants of congenital disorders of glycosylation (CDG-1). Dr. Gilmore has remained at UMMS and is currently a Professor and Vice-Chair of the Department of Biochemistry and Molecular Pharmacology.

Molecular Basis of Congenital Deficiencies of GPI Anchors

Taroh KinoshitaProfessor
Immunology Frontier Research Center and Research Institute for Microbial Diseases
Osaka University


Dr. Taroh Kinoshita started his research career in 1974 with studies on bactericidal insect proteins at the University of Tokyo. During PhD course in Osaka University Medical School, he studied mammalian complement system. He did 3-year post-doctoral research in New York University School of Medicine from 1982. He demonstrated that blood cells from patients with paroxysmal nocturnal hemoglobinuria (PNH) consist of normal cells and cells deficient in decay-accelerating factor (DAF), and that the latter population is highly sensitive to complement, showing the critical role of DAF in self-nonself discrimination in the complement system. From 1985 to 1990, as a Research Associate and then an Assistant Professor in Osaka University Medical School, he studied mouse complement receptors and demonstrated that complement receptor type 2 is important for antibody response. From 1990 to date, as a Professor in the Research Institute for Microbial Diseases, Osaka University, he has been studying biosynthesis of glycosylphosphatidylinositol (GPI)-anchor and molecular basis of PNH. In 1993, he for the first time cloned PIGA gene that is required for GPI biosynthesis. Since then, he has cloned most of the genes involved in GPI pathway. He demonstrated that PIGA mutation causes deficiency of GPI-anchor in PNH and that PIGA mutation occurs somatically in hematopoietic stem cell, clarifying acquired nature of the disease and why only blood cells are affected. From 2003 to 2007, he was Director of the Research Institute for Microbial Diseases, Osaka University. From 2007, he has been a Deputy-Director of WPI Immunology Frontier Research Center, Osaka University. In last 5 years, he has actively contributed in studies identifying and characterizing congenital deficiencies of GPI.

The CDG Family Conference will be held at the Clarion Del Mar Inn in nearby Del Mar Sunday February 28–Monday February 29, 2016. We will bridge the two meetings with a patient-centric “doctor-is-in” session the afternoon of Saturday, February 27, followed by an interactive networking reception that promotes conversations among scientists, physicians, families and advocates. 

Stories in The New Yorker and Der Spiegel last year attest to the symposium’s success at bridging borders in rare disease, and this year will be no different. Join us. 

Please note (updated February 23): Due to unforeseen circumstances, Drs. Hood and Eklund will not be able to join the symposium this year. Please see our revised program below. Remaining space in the La Jolla auditorium is limited; late registrations may be wait-listed.
