MetabolomicsViral-Induced Heme Accumulation Subverts TLR4bb-Mediated Antiviral Immunity by Triggering Gut Microbiota Dysbiosis, Metabolic Dysregulation, and Ferroptosis

This study identifies grass carp TLR4bb as a crucial hub coordinating antiviral immunity with heme metabolism, redox balance, and gut microbiota during GCRV-II infection. While TLR4bb recruits TIRAP/MyD88/TRIF to activate IFN signaling against the virus, its synergy with heme and viral sensing tr...

TranscriptomicsGATA-1 and heme regulate the erythroid cell transcriptome.
Alas2 gene encodes the rate-limiting enzyme in heme biosynthesis. CRISPR/Cas9-mediated ablation of two Alas2 intronic cis-elements strongly reduced GATA-1-induced Alas2 transcription, heme biosynthesis, and GATA-1 regulation of other vital constituents of the erythroid cell transcriptome. Bypassing ...

TranscriptomicsPorphyromonas gingivalis W50 Heme-excess vs Heme-limitation
Transcription profiling of P. gingivalis W50 grown in continuous culture under conditions of heme-excess and heme-limitation. Reference design (using Cy5 labelled genomic DNA as the reference) to compare two conditions: heme-excess vs heme-limitation. Three samples for each condition, independently...

ProteomicsDepletion Assisted Hemin Affinity (DAsHA) Proteomics Reveals an Expanded Landscape of Heme Binding Proteins in the Human Proteome
Heme b (iron protoporphyrin IX) plays important roles in biology as a metallocofactor and signaling molecule. However, the targets of heme signaling and the network of proteins that mediate the exchange of heme from sites of synthesis or uptake to heme dependent or regulated proteins are poorly unde...

ProteomicsProfiling the heme-binding proteomes of bacteria using chemical proteomics
Heme is a cofactor with myriad roles and is essential to almost all living organisms. Accordingly, bacte-rial pathogens have developed numerous mechanisms to acquire heme from their hosts. Beyond classi-cal gas transport and catalytic functions, heme is increasingly appreciated as a tightly controll...

MetabolomicsATAD3A has a scaffolding role regulating mitochondria inner membrane structure and protein assembly

The ATPase Family AAA Domain Containing 3A (ATAD3A), is a mitochondrial inner membrane protein conserved in metazoans. ATAD3A has been associated with several mitochondrial functions, including nucleoid organization, cholesterol metabolism, and mitochondrial translation. To address its primary ro...

TranscriptomicsThe two-component system ChrSA is crucial for heme tolerance and interferes with HrrSA in heme-dependent gene regulation in Corynebacterium glutamicum
We recently showed that the two-component system (TCS) HrrSA plays a central role in the control of heme homeostasis in the Gram-positive soil bacterium Corynebacterium glutamicum. Here, we characterized the function of another TCS of this organism, ChrSA, which exhibits significant sequence similar...

ProteomicsStructural basis for heme-dependent NCoR binding to the transcriptional repressor REV-ERBβ
Heme is the endogenous ligand for the constitutively repressive REV-ERB nuclear receptors, REV-ERBα (NR1D1) and REV-ERBβ (NR1D2), but how heme regulates REV-ERB activity remains unclear. While cellular studies indicate heme is required for the REV-ERBs to bind the corepressor NCoR and repress transc...
