TABLE 3.

ER Proteins with Different Expression Levels in Fractions 8 (Juvenile) and 10 (Aged)

  • CaBP1 (A↑)

  • Valosin-containing protein (A↑)

  • Proteasome subunit beta type 4 precursor (J↑)

  • Pregnancy-zone protein (A↑)

  • Similar to Rap1 guanine nucleotide-exchange factor PDZ-GEF2B (A↑)

  • Ba1-647 (J↑)

  • Alpha-2-HS-glycoprotein (J↑)

Proteins identified from 2D gel spots (using IPG pH 5–8 strips) occurring in aged fraction 10 and juvenile fraction 8 with at least a twofold difference in expression levels in two-dimensional gel electrophoresis identified by mass spectrometry. Only selected spots were analyzed.
