Characterization of a novel HMG-CoA lyase enzyme with a dual location in endoplasmic reticulum and cytosol
(American Society for Biochemistry and Molecular Biology, 2012)
A novel lyase activity enzyme is characterized for the first time: HMG-CoA lyase-like1 (er-cHL), which is a close homolog of mitochondrial HMG-CoA lyase (mHL). Initial data show that there are nine ...
Identification of conserved amino acid residues in rat liver carnitine palmitoyltransferase I critical for malonyl-CoA inhibition. Mutation of methionine 593 abolishes malonyl-CoA inhibition
(American Society for Biochemistry and Molecular Biology, 2003-03-14)
Carnitine palmitoyltransferase (CPT) I, which catalyzes the conversion of palmitoyl-CoA to palmitoylcarnitine facilitating its transport through the mitochondrial membranes, is inhibited by malonyl-CoA. ...
The return of malonyl-CoA to the brain: cognition and other stories
(Elsevier, 2021-01)
Nutrients, hormones and the energy sensor AMP-activated protein kinase (AMPK) tightly regulate the intracel-lular levels of the metabolic intermediary malonyl-CoA, which is a precursor of fatty ...
Astrocytes and oligodendrocytes in grey and white matter regions of the brain metabolize fatty acids
(Springer Nature, 2017-09-07)
The grey and white matter regions of the mammalian brain consist of both neurons and neuroglial cells. Among the neuroglia, the two macroglia oligodendrocytes and astrocytes are the most abundant cell ...
Sensing of nutrients by CPT1C controls SAC1 activity to regulate AMPA receptor trafficking
(Rockefeller University Press, 2020)
Carnitine palmitoyltransferase 1C (CPT1C) is a sensor of malonyl-CoA and is located in the ER of neurons. AMPA receptors (AMPARs) mediate fast excitatory neurotransmission in the brain and play a key ...
Structural (betaalpha) 8 TIM barrel model of 3-hydroxy-3-methylglutaryl-coenzyme A lyase
(American Society for Biochemistry and Molecular Biology, 2003)
This study describes three novel homozygous missense mutations (S75R, S201Y, and D204N) in the 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) lyase gene, which caused 3-hydroxy-3-methylglutaric aciduria in ...
Sensing of nutrients by CPT1C regulates late endosome/lysosome anterograde transport and axon growth
(eLife Sciences Publications, 2019)
Anterograde transport of late endosomes or lysosomes (LE/Lys) is crucial for proper axon growth. However, the role of energetic nutrients has been poorly explored. Malonyl-CoA is a precursor of fatty ...
CPT1c is localized in endoplasmic reticulum of neurons and has carnitine palmitoyltransferase activity
(American Society for Biochemistry and Molecular Biology, 2008)
CPT1c is a carnitine palmitoyltransferase 1 (CPT1) isoform that is expressed only in the brain. The enzyme has recently been localized in neuron mitochondria. Although it has high sequence identity with ...
Mechanisms of CPT1C-Dependent AMPAR trafficking enhancement
(Frontiers Media, 2018-08-08)
In neurons, AMPA receptor (AMPAR) function depends essentially on their constituent
components: the ion channel forming subunits and ion channel associated proteins.
On the other hand, AMPAR trafficking ...
Defective in mitotic arrest 1 (Dma1) ubiquitin ligase controls G1 cyclin degradation
(American Society for Biochemistry and Molecular Biology, 2013-02)
Progression through the G1 phase of the cell cycle is controlled by diverse cyclin-dependent kinases (CDKs) that might be associated to numerous cyclin isoforms. Given such complexity, regulation of ...
