High impact information on CYTB

  • Affinity-purified rabbit anti-neutrophil cytochrome b light or heavy chain antibodies were used to immunocytochemically and biochemically localize cytochrome b in neutrophils and eosinophils [1].
  • However, the system showed high O2(-)-generating activity of 31.8 mol/s/mol of cytochrome b558 (52.5% of the original O2(-)-generating activity of the solubilized membranes) in the presence of a nitro blue tetrazolium (NBT) reductase fraction that was separated from the cytochrome b fraction by heparin-Sepharose chromatography [2].
  • Furthermore, mRNA transcripts from these nuclear genes encoding mitochondrial proteins did not increase to the same extent as mRNA transcripts of mitochondrial genes such as cytochrome b, which increased 5.9-fold after 21 days of stimulation [3].
  • When cardiac muscle and Type I (red, oxidative) skeletal muscle were compared to Type II (white, glycolytic) skeletal muscle, mitochondrial DNA, mitochondrial ribosomal RNA, and cytochrome b mRNA, each increased in direct proportion to increases in oxidative capacity [4].
  • We demonstrated an upregulation of the U6 snRNA binding protein Lsm5, cytochrome b, an expressed sequence tag, and the actin-depolymerizing factor cofilin2 mRNA in collateral arteries 24h after femoral ligation [5].
 

Biological context of CYTB

 

Anatomical context of CYTB

  • Furthermore, when the phenotypic characteristics of Type II skeletal muscle were altered by electrical stimulation in vivo, mitochondrial DNA, mitochondrial rRNA, and cytochrome b mRNA also increased proportionately with increases in oxidative capacity [4].
  • Differential responses of mitochondrial respiration and cytochrome b redox states in the presence and absence of magnesium indicate that with magnesium present, heart mitochondria retain the ability to phosphorylate ADP after calcium uptake [9].
