Toward decoding spatiotemporal signaling activities of reactive immunometabolites with precision immuno-chemical biology tools

Yimon Aye, Kuan-Ting Huang

Immune-cell reprogramming driven by mitochondria-derived reactive electrophilic immunometabolites (mt-REMs—e.g., fumarate, itaconate) is an emerging phenomenon of major biomedical importance. Despite their localized production, mt-REMs elicit significantly ...

Let's get biophysical - How to get your favorite protein's digits☆

Yimon Aye

In these days of information overload and high-throughput analysis, it is easy to lose focus on the study of individual proteins. It is our conjecture that such investigations are still crucially important and offer uniquely penetrative insights. We thus p ...

Climbing into their Skin to Understand Contextual Protein-Protein Associations and Localizations: Functional Investigations in Transgenic Live Model Organisms

Yimon Aye

Borrowing some quotes from Harper Lee's novel "To Kill A Mockingbird" to help frame our manuscript, we discuss methods to profile local proteomes. We initially focus on chemical biology regimens that function in live organisms and use reactive biotin speci ...

Formaldehyde regulates one-carbon metabolism and epigenetics

Yimon Aye

Recently, Pham et al. used an array of model systems to uncover a role for the enzyme methionine adenosyltransferase (MAT) -1A, which is mainly expressed in liver, in both sensing formaldehyde and regulating transcriptional responses that protect against i ...

Tag, you're it: G-ICAT identifies p120-cysteine glutathionylation triggering E-cadherin destabilization

Yimon Aye

Current methods have limited ability in directly quantifying the extent of glutathionylation on specific proteincysteines. In this issue of Cell Chemical Biology, Ahn et al.1 report G-ICAT (glutathione-based isotope-coded affinity tag), aimed at addressing ...

Structural Insights into Electrophiles and Electrophilic Metabolites Sensing and Signaling: The Missing Information

Yimon Aye, Chloé Rogg

Native reactive electrophilic species (RES) are long-recognized regulators of pathophysiology; yet, knowledge surrounding how RES regulate context-specific biology remains limited. The latest technological advances in profiling and precision decoding of RE ...

Z-REX: shepherding reactive electrophiles to specific proteins expressed tissue specifically or ubiquitously, and recording the resultant functional electrophile-induced redox responses in larval fish

Yimon Aye, Sruthi Raja, Kuan-Ting Huang

This Protocol Extension describes the adaptation of an existing Protocol detailing the use of targetable reactive electrophiles and oxidants, an on-demand redox targeting toolset in cultured cells. The adaptation described here is for use of reactive elect ...

Monitoring On-Target Signaling Responses in Larval Zebrafish- Z-REX Unmasks Precise Mechanisms of Electrophilic Drugs and Metabolites

Yimon Aye, Jesse Poganik, Kuan-Ting Huang, Phillippe Ly

Reactive metabolites and related electrophilic drugs are among the most challenging small molecules to study. Conventional approaches to deconstruct the mode of action (MOA) of such molecules leverage bulk treatment of experimental specimens with an excess ...

Keap It in the Family: How to Fish out New Paradigms in Keap1-Mediated Cell Signaling

Yimon Aye, Kuan-Ting Huang

Keap1 is associated with cytoprotective signaling. These roles of Keap1 typically focus on its role as a degrader of the antioxidant response (AR) transcription factor, Nrf2, and the inhibition of this process upon Keap1 labeling by electrophiles. However, ...
