| Research Abstract |
Coenzyme Q10 (CoQ10) is necessary for ATP biosynthesis. It also is an antioxidant. Saposin B (SapB) is a CoQ10 binding protein.Analysis using prosaposin (Psap, precursor of SapB) knockout mouse revealed that concentrations of exogenous CoQ10 in plasma and liver were significantly reduced in homo-type animal. Psap transfectant (Tf) and knockdown (KD) HepG2 cells are established. CoQ10 contents decreased as follows: Tf > parent > KD. These data imply that SapB and/orits precursor Psap is a modulator for CoQ10 contents.
