Calorie Restriction Promotes Mammalian Cell Survival by Inducing the SIRT1 Deacetylase
A major cause of aging is thought to result from the cumulative effects of cell loss over time. In yeast, caloric restriction (CR) delays aging by activating the Sir2 deacetylase. Here we show that… Expand
Acetylation of the C terminus of Ku70 by CBP and PCAF controls Bax-mediated apoptosis.
Apoptosis is a key tumor suppression mechanism that can be initiated by activation of the proapoptotic factor Bax. The Ku70 DNA end-joining protein has recently been shown to suppress apoptosis by… Expand
Variant PRC1 Complex-Dependent H2A Ubiquitylation Drives PRC2 Recruitment and Polycomb Domain Formation
Summary Chromatin modifying activities inherent to polycomb repressive complexes PRC1 and PRC2 play an essential role in gene regulation, cellular differentiation, and development. However, the… Expand
KDM2B links the Polycomb Repressive Complex 1 (PRC1) to recognition of CpG islands
CpG islands (CGIs) are associated with most mammalian gene promoters. A subset of CGIs act as polycomb response elements (PREs) and are recognized by the polycomb silencing systems to regulate… Expand

A C‐terminally modified ubiquitin (Ub) derivative, ubiquitin vinyl sulfone (UbVS), was synthesized as an active site‐directed probe that irreversibly modifies a subset of Ub C‐terminal hydrolases… Expand
Chemistry-based functional proteomics reveals novel members of the deubiquitinating enzyme family.
The ubiquitin (Ub)-proteasome system includes a large family of deubiquitinating enzymes (DUBs). Many members are assigned to this enzyme class by sequence similarity but without evidence for… Expand
Renal Cyst Formation in Fh1-Deficient Mice Is Independent of the Hif/Phd Pathway: Roles for Fumarate in KEAP1 Succination and Nrf2 Signaling
Summary The Krebs cycle enzyme fumarate hydratase (FH) is a human tumor suppressor whose inactivation is associated with the development of leiomyomata, renal cysts, and tumors. It has been proposed… Expand
Activity-based chemical proteomics accelerates inhibitor development for deubiquitylating enzymes.
Converting lead compounds into drug candidates is a crucial step in drug development, requiring early assessment of potency, selectivity, and off-target effects. We have utilized activity-based… Expand
A small molecule inhibitor of ubiquitin-specific protease-7 induces apoptosis in multiple myeloma cells and overcomes bortezomib resistance.
Bortezomib therapy has proven successful for the treatment of relapsed/refractory, relapsed, and newly diagnosed multiple myeloma (MM); however, dose-limiting toxicities and the development of… Expand
A deubiquitinating enzyme encoded by HSV-1 belongs to a family of cysteine proteases that is conserved across the family Herpesviridae.

We have discovered a ubiquitin (Ub)-specific cysteine protease encoded within the N-terminal approximately 500 residues of the UL36 gene product, the largest (3164 aa) tegument protein of herpes… Expand
