Antibodies confer humoral immunity but can also be harmful when they target an autoantigen, alloantigen, allergen, or biotherapeutic. New strategies are needed for antigen-specific suppression of undesired antibody responses, particularly to T cell–dependent protein antigens, because they elicit...

Beads-on-a-string, characterization of ETS-1 sumoylated within its flexible N-terminal sequence
Download2006
Mackereth, Cameron D., Graves, Barbara J., Macauley, Matthew S., Schärpf, Manuela, McIntosh, Lawrence P. , Blaszczak, Adam G., Errington, Wesley J.
Sumoylation regulates the activities of several members of the ETS transcription factor family. To provide a molecular framework for understanding this regulation, we have characterized the conjugation of Ets-1 with SUMO-1. Ets-1 is modified in vivo predominantly at a consensus sumoylation motif...

Disubstituted sialic acid ligands targeting siglecs CD33 and CD22 associated with myeloid leukaemias and B cell lymphomas

McBride, Ryan, Fokin, Valery V., He, Yuan, Macauley, Matthew S., Paulson, James C. , Arlian, Britni M., Rillahan, Cory D., Rangarajan, Janani, Schwartz, Erik
The siglec family of sialic acid-binding proteins are endocytic immune cell receptors that are recognized as potential targets for cell directed therapies. CD33 and CD22 are prototypical members and are validated candidates for targeting acute myeloid leukaemia and non-Hodgkin's lymphomas due to...

Elevation of global O-GlcNAc levels in 3T3-L1 adipocytes by selective inhibition of O-GlcNAcase does not induce insulin resistance
Download2008
Bubb, Abigail K., Macauley, Matthew S., Davies, Gideon J., Vocadlo, David J. , Martinez-Fleites, Carlos
The O-GlcNAc post-translational modification is considered to act as a sensor of nutrient flux through the hexosamine biosynthetic pathway. A cornerstone of this hypothesis is that global elevation of protein O-GlcNAc levels, typically induced with the non-selective O-GlcNAcase inhibitor PUGNAc...

Holes in the glycan shield of the native HIV envelope are a target of trimer-elicited neutralizing antibodies

Hsueh, Jessica, Menis, Sergey, Sanders, Rogier W., Ozorowski, Gabriel, Pauthner, Matthias, Voss, James E., van Gils, Marit J., Torres, Jonathan L., McCoy, Laura E., Ward, Andrew B., Wilson, Ian A., Schief, William R., Macauley, Matthew S., Burton, Dennis R., Cottrell, Christoph A., Messmer, Terrence, Sok, Devin, Briney, Bryan, Kulp, Daniel W.
A major advance in the search for an HIV vaccine has been the development of a near-native Envelope trimer (BG505 SOSIP.664) that can induce robust autologous Tier 2 neutralization. Here, potently neutralizing monoclonal antibodies (nAbs) from rabbits immunized with BG505 SOSIP.664 are shown to...

Metabolism of vertebrate amino sugars with N-glycolyl groups: Intracellular β-O-linked N-glycolylglucosamine (GlcNGc), UDP-GlcNGc,and the biochemical and structural rationale for the substrate tolerance of β-O-linked& beta;-N-acetylglucosaminidase

Vocadlo, David J. , Chan, Jefferson, Whitworth, Garrett A., Macauley, Matthew S., Stubbs, Keith A., Varki, Ajit, Davies, Gideon J., Yuzwa, Scott, Zandberg, Wesley, Bennet, Andrew J., He, Yuan
The O-GlcNAc modification involves the attachment of single β-O-linked N-acetylglucosamine residues to serine and threonine residues of nucleocytoplasmic proteins. Interestingly, previous biochemical and structural studies have shown that O-GlcNAcase (OGA), the enzyme that removes O-GlcNAc from...

O-GlcNAcase uses substrate-assisted catalysis Kinetic analysis and development of highly selective mechanism-inspired inhibitors

Vocadlo, David J., Whitworth, Garrett E., Macauley, Matthew S., Debowski, Aleksandra W., Chin, Danielle
The post-translational modification of serine and threonine residues of nucleocytoplasmic proteins with 2-acetamido-2-deoxy-d-glucopyranose (GlcNAc) is a reversible process implicated in multiple cellular processes. The enzyme O-GlcNAcase catalyzes the cleavage of β-O-linked GlcNAc (O-GlcNAc)...

Streptococcus pneumoniae endohexosaminidase D, structural and mechanistic insight into substrate-assisted catalysis in family 85 glycoside hydrolases
Download2009
Abbott, D. W., Boraston, Alisdair B. , Vocadlo, David J., Macauley, Matthew S.
Endo-β-d-glucosaminidases from family 85 of glycoside hydrolases (GH85 endohexosaminidases) act to cleave the glycosidic linkage between the two N-acetylglucosamine units that make up the chitobiose core of N-glycans. Endohexosaminidase D (Endo-D), produced by Streptococcus pneumoniae, is...

Okon, Mark, Schulman, Brenda A., Macauley, Matthew S., McIntosh, Lawrence P., Mackereth, Cameron D., Schärpf, Manuela, Errington, Wesley J.
Although sumoylation regulates a diverse and growing number of recognized biological processes, the molecular mechanisms by which the covalent attachment of the ubiquitin-like protein SUMO can alter the properties of a target protein remain to be established. To address this question, we have...

Sialic acid terminates glycans of glycoproteins and glycolipids that play numerous biological roles in health and disease. Although genetic tools are available for interrogating the effects of decreased or abolished sialoside expression in mice, pharmacological inhibition of the sialyltransferase...
