July 2017 – Congratulations to Sally and Cindy; their paper entitled Structural and functional characterization of the histidine phosphatase domains of human Sts-1 and Sts-2 was just accepted for publication in Biochemistry.
May 2017 – Sally gave a great talk at the annual Biochemistry and Cell Biology retreat entitled ‘Phosphatase Suppressor of T-cell Receptor Signaling Pathway as a Novel Drug Target for Systemic Candidiasis’. Sally will also present a poster on this topic at the annual meeting of the American Crystallographic Association in New Orleans at the end of this month.
May 2017 – Best of luck to the latest French lab graduates, Tylene Hilaire (off to Penn. State for a PhD in Chemistry), Michael Yan (working at Enzo Biosciences while applying to medical schools), Andrew Tsai (applying to medical school), and Brian Coyne (currently completing his MS in Chemistry in our lab). The lab has benefited substantially from all of your great efforts – thanks for everything.
May 2017 – Two of our undergraduates presented their work at the annual Chemistry Department Senior Research Symposium. Brian Coyne presented his work on the ‘Analysis of Putative Nuclear Localization Sequence Mutagenesis on vFGAMS Nuclear Import’ and Tylene Hilaire presented her work on ‘Developing an Assay for the Kinetic Measurement of Nucleobase Transporters.’
April 2017 – Two of our undergraduate researchers, Andrew Tsai and Tylene Hilaire, presented posters at the URECA undergraduate research symposium. Andrews poster was entitled ‘Characterization of Nucleobase and Nucleoside Transporters in Humans and E. coli‘ and Tylene’s poster was entitled ‘Developing an Assay for the Kinetic Measurement of Nucleobase Transporters’.
March 2017 – Congratulations to Andrew Tsai for being awarded a Stony Brook University Undergraduate Recognition Award for Academic Excellence. A well-deserved honor.
January 2017 – Congratulations to Iva, Deb and Sally; their review of Higher order structures in purine and pyrimidine metabolism was recently accepted for publication in the Journal of Structural Biology.
January 2017 – Congratulations to James for his recent paper in J. Phys. Chem. B, completed in collaboration with the Tonge Lab, entitled Femtosecond to Millisecond Dynamics of Light Induced Allostery in the Avena Sativa Lov Domain.
January 2017 – Jarrod gave an invited talk on The Complex problem of Purine Biosynthesis at the New York Structural Biology Discussion Group’s 12th Winter Meeting at the New York Academy of Sciences

May 2016 – Roger, Iva, Deb and Sally attended a BioSAXS workshop held at the Advanced Photon Source at Argonne National Laboratory.
May 2016 – Congratulations to Andrew and Tylene for being selected for a PSEG URECA fellowship and an Explorations in STEM fellowship, respectively, for summer research in our lab.
Feb. 2016 – Congratulations to Kafi for being selected as a W. Burghardt Turner Graduate Fellow.
Jan. 2016 – Congratulations to James for being selected for a second year to the Chemical Biology Training Program.
The suppressor of T-cell signaling (Sts) class of proteins has emerged as a potentially important target for immune regulation. Work from our collaborators lab has shown that mice lacking the Sts-1 and Sts-2 proteins are profoundly resistant to infection by deadly pathogens, including C. albicans. The structure above (solved at 1.87 Å) shows the histidine phosphatase domain of human Sts-1 in complex with sulfate. Structures of this catalytic domain of Sts-1 form the foundation of a long-term, structure-guided drug discovery program aimed at developing immuno-stimulatory therapies to treat deadly pathogen infections.
