Proteomic Analysis of Rat Liver Peroxisome
Open accessAbstract
Subcellular proteomics, which includes isolation of subcellular components prior to a proteomic analysis, is advantageous not only in characterizing large macro-molecular complexes such as organelles but also in elucidating mechanisms of protein transport and organelle biosynthesis. Because of the high sensitivity achieved by the present proteomics technology, the purity of samples to be analyzed is important for the interpretation of the results obtained. In the present study, peroxisomes isolated from rat liver by usual cell fractionation were further purified by immunoisolation using a specific antibody raised against a peroxisomal membrane protein, PMP70. The isolated peroxisomes were analyzed by SDS-PAGE combined with liquid chromatography/mass spectrometry. Altogether 34 known peroxisomal proteins were identified in addition to several mitochondrial and microsomal proteins. Some of the latter may reside in the peroxisomes as well. Analysis of membrane fractions identified all known peroxins except for Pex7. Two new peroxisomal proteins of unknown function were of high abundance. One is a bi-functional protein consisting of an aminoglycoside phosphotransferase-domain and an acyl-CoA dehydrogenase domain. The other is a newly identified peroxisome-specific isoform of Lon protease, an ATP-dependent protease with chaperone-like activity. The peroxisomal localization of the protein was confirmed by immunological techniques. The peroxisome-type Lon protease, which is distinct from the mitochondrial isoform, may play an important role in the peroxisomal biogenesis.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
