Litteral:
"Subcellular fractionation of rat forebrain showed TRIM3 to be particularly abundant in the light membrane fraction (P3), and sparse in the cytosol (S3) (Figure 2C). TRIM3 was also present in the Triton X-100-resistant PSD fractions (PSDI and PSD II), which corroborates its detection in the PSD by mass spectrometry [22]. However, TRIM3 is not enriched in the PSD like PSD-95 and is extracted by Sarkosyl detergent (PSDIII), indicating that TRIM3 is not tightly associated with the PSD (Figure 2B).

By immunostaining, TRIM3 was widely distributed in a micropunctate pattern throughout the cell body, axon, and dendrites of cultured hippocampal neurons (Figure 2C)"
