Electrophile Signaling and Emerging Immuno- and Neuro-modulatory Electrophilic Pharmaceuticals

Yimon Aye, Jesse Poganik

With a lipid-rich environment and elevated oxygen consumption, the central nervous system (CNS) is subject to intricate regulation by lipid-derived electrophiles (LDEs). Investigations into oxidative damage and chronic LDE generation in neural disorders ha ...

The mRNA-Binding Protein HuR Is a Kinetically-Privileged Electrophile Sensor

Yimon Aye, Jesse Poganik, Yi Zhao, Alexandra Krina Van Hall-Beauvais

The key mRNA-binding proteins HuR and AUF1 are reported stress sensors in mammals. Intrigued by recent reports of sensitivity of these proteins to the electrophilic lipid prostaglandin A2 and other redox signals, we here examined their sensing abilities to ...

REX technologies for profiling and decoding the electrophile signaling axes mediated by Rosetta Stone proteins

Yimon Aye, Daniel Ahmet Urul

It is now clear that some cysteines on some proteins are highly tuned to react with electrophiles. Based on numerous studies, it is also established that electrophile sensing underpins rewiring of several critical signaling processes. These electrophile-se ...

The more the merrier: how homo-oligomerization alters the interactome and function of ribonucleotide reductase

Yimon Aye, Alexandra Krina Van Hall-Beauvais

Stereotyped as a nexus of dNTP synthesis, the dual-subunit enzyme - ribonucleotide reductase (RNR) - is coming into view as a paradigm of oligomerization and moonlighting behavior. In the present issue of `omics', we discuss what makes the larger subunit o ...

Proteomics and Beyond: Cell Decision-Making Shaped by Reactive Electrophiles

Yimon Aye, Xuyu Liu

Revolutionary proteomic strategies have enabled rapid profiling of the cellular targets of electrophilic small molecules. However, precise means to directly interrogate how these individual electrophilic modifications at low occupancy functionally reshape ...

Post-transcriptional regulation of Nrf2-mRNA by the mRNA-binding proteins HuR and AUF1

Yimon Aye, Jesse Poganik, Xuyu Liu

The nuclear factor erythroid 2 related factor 2 (Nrf2) signaling axis is a target of covalent drugs and bioactive native electrophiles. However, much of our understanding of Nrf2 regulation has been focused at the protein level. Here we report a post-trans ...

Chemical Biology Gateways to Mapping Location, Association, and Pathway Responsivity

Yimon Aye, Xuyu Liu

Here we discuss, how by applying chemical concepts to biological problems, methods have been developed to map spatiotemporal regulation of proteins and small-molecule modulation of proteome signaling responses. We outline why chemical-biology platforms are ...
