Webb2 feb. 2010 · Poly(ADP-ribose)-1 (PARP-1) is a key mediator of cell death in excitotoxicity, ischemia, and oxidative stress. PARP-1 activation leads to cytosolic NAD + depletion and mitochondrial release of apoptosis-inducing factor (AIF), but the causal relationships between these two events have been difficult to resolve. Here, we examined this issue by … WebbMitochondria are organelles that contain their own DNA, and have both inner and outer membranes. Mitochondria are often referred to as the "powerhouses of the cell" because …
Webb9 apr. 2024 · In mitochondria, two phage-like single-peptide polymerases are active (RPOTm and RPOTmp). In plastids, we know of at least three DNA-dependent RNA polymerases, namely plastid encoded polymerase (PEP) that represents a multi-subunit enzyme reminiscent of bacterial polymerases, plus two phage-like single-peptide … Webb23 jan. 2024 · However, in this study we show that endogenous MacroD1 protein is highly enriched within mitochondria. We also show that MacroD1 is highly expressed in human and mouse skeletal muscle. Furthermore, we show that MacroD1 can efficiently remove ADP-ribose from 5′ and 3′-phosphorylated double stranded DNA adducts in vitro.
Webb23 jan. 2024 · Overall, we have shown that MacroD1 is a mitochondrial protein with promiscuous enzymatic activity that can target the ester bonds of ADP-ribosylated phosphorylated double-stranded DNA ends. These findings have exciting implications for MacroD1 and ADP-ribosylation within the regulation of mitochondrial function and DNA …

Mitochondria‐associated endoplasmic reticulum (ER) membranes (MAMs) serve as essential hubs for many biological pathways, such as autophagy and mitochondria fission and fusion. cheap grocery stores in davisWebb1 jan. 2024 · Mitochondria regulate a multitude of metabolic and signaling pathways, but their primary function is the production of ATP. When mitochondrial function is compromised, there can be a reduced efficiency of cellular respiration and thus a loss of ATP production.
