Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

PRP-1, a toll-like receptor ligand, upregulates the unfolded protein response in human chondrosarcoma cells

Cancer Treatment and Research Communications, 2022
Background: Previous studies showed that proline-rich polypeptide (PRP-1) is a ligand for innate immunity toll-like receptors (TLR), and an inhibitor of the mammalian target of rapamycin complex 1 (mTORC1) which induces the death of chondrosarcoma cancer

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Activating Transcription Factor 4 (ATF4) Regulates Neuronal Activity by Controlling GABA_BR Trafficking. [PDF]

J Neurosci, 2018
Activating Transcription Factor 4 (ATF4) has been postulated as a key regulator of learning and memory. We previously reported that specific hippocampal ATF4 downregulation causes deficits in synaptic plasticity and memory and reduction of glutamatergic functionality. Here we extend our studies to address ATF4's role in neuronal excitability.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

HOXA10 controls osteoblastogenesis by directly activating bone regulatory and phenotypic genes [PDF]

, 2007
HOXA10 is necessary for embryonic patterning of skeletal elements, but its function in bone formation beyond this early developmental stage is unknown. Here we show that HOXA10 contributes to osteogenic lineage determination through activation of Runx2 ...

ATF4 promotes renal tubulointerstitial fibrosis through hexokinase II-mediated glycolysis

Frontiers in Immunology
BackgroundRenal tubulointerstitial fibrosis is a reliable predictor of progressive chronic kidney disease (CKD). Activating transcription factor 4 (ATF4) has recently emerged as a pivotal player in multiple pathophysiologic processes, particularly the ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

CONSERVED FUNCTIONAL DOMAINS OF THE RNA-POLYMERASE-III GENERAL TRANSCRIPTION FACTOR BRF [PDF]

, 1994
In Saccharomyces cerevisiae, two components of the RNA polymerase III (Pol III) general transcription factor TFIIIB are the TATA-binding protein (TBP) and the B-related factor (BRF), so called because its amino-terminal half is homologous to the Pol II ...
