Physiological adaptation to proteotoxic stress in the endoplasmic reticulum (ER) requires retrotranslocation of misfolded proteins into the cytoplasm for ubiquitination and elimination by ER-associated degradation (ERAD). A surprising paradox emerging from recent studies is that ubiquitin ligases (E3s) and deubiquitinases (DUBs), enzymes with opposing activities, can both promote ERAD. Here we ...
In recent years, the size and dynamics of the global routing table have increased rapidly along with an increase in the number of edge networks. The relation between edge network quantity and routing table size/dynamics reveals a major limitation in the current architecture; there is a conflict between provider-based address aggregation and edge networks’ need for multihoming. Two basic directi...
Deubiquitylating enzymes (DUBs) reverse the ubiquitylation of target proteins, thereby regulating diverse cellular functions. In contrast to the plethora of research being conducted on the ability of DUBs to counter the degradation of cellular proteins or auto-ubiquitylated E3 ligases, very little is known about the mechanisms of DUB regulation. In this review paper, we summarize a novel possib...
A20 (also known as TNFAIP3) is a deubiquitinating enzyme (DUB) that ensures optimal immune responses in cells stimulated by cytokines, such as TNF and IL-1, or pathogen components, such as lipopolysaccharide. Deletion of A20 in mice results in multi-organ inflammation and death within 2 weeks [1]. The anti-inflammatory functions of A20 have been attributed to its ability to negatively regulate ...
Ubiquitin chains are important post-translational modifications that control a large number of cellular processes. Chains can be formed via different linkages, which determines the type of signal they convey. Deubiquitylating enzymes (DUBs) regulate ubiquitylation status by trimming or removing chains from attached proteins. DUBs can contain several ubiquitin-binding pockets, which confer speci...
Oncogenic forms of the kinase FLT3 are important therapeutic targets in acute myeloid leukemia (AML); however, clinical responses to small-molecule kinase inhibitors are short-lived as a result of the rapid emergence of resistance due to point mutations or compensatory increases in FLT3 expression. We sought to develop a complementary pharmacological approach whereby proteasome-mediated FLT3 de...
Endometrial ablation is one of the most effective methods for treatment of dysfunctional uterine bleeding (DUB). Balloon devices with circulating hot water inside or electrodes on the outer surface and radiofrequency-induced thermal destructors are the most recently introduced available tools for endometrial ablation. All of these methods are effective and simple but expensive technologies. The...
Posttranslational modification of proteins by ubiquitin regulates synapse development and synaptic transmission. Much progress has been made investigating the role of ubiquitin ligases at the synapse, however very little is known about the deubiquitinating enzymes (DUBs) which remove ubiquitin from target proteins. Although there are far fewer DUBs than ubiquitin ligases encoded by the human ge...
Distance (upper)-bounding (DUB) allows a verifier to know whether a proving party is located within a certain distance bound. DUB protocols have many applications in secure authentication and location based services. We consider the dual problem of distance lower bounding (DLB), where the prover proves it is outside a distance bound to the verifier. We motivate this problem through a number of ...
