Proteins enriched in ERMAP fraction.

List of significantly enriched proteins (pFigure 5, lane 9) compared to the control sample (“RNase−”, see Figure 5, lane 10) as analyzed by mass spectrometry (for a larger list, see Table S1). Included in the table are the Entrez Gene ID, average number (“AVG”), and standard deviation (“STD”) of peptides from the analyses performed on three independent experiments. In addition the average number of peptides from all the components of the MSC was also tabulated, some of which p>0.05. The p values were determined using a paired two-tailed Student t test. On average, 2,427±311 total peptides were recovered from the RNase+ samples, and 1,684±266 total peptides were recovered from the RNase− samples.arRNA or snRNA binding protein.bPrimarily involved in DNA binding but has been reported to bind to RNA.cMembers of the MSC where p>0.05.
