Mass-spectrometry results of HA-tagged TBP55 co-immunoprecipitation.

Co-IP assay followed by mass-spectrometry analysis were performed as described in Materials and methods. Frequency of identification indicates the frequency for one protein to be detected in an exclusive or enriched manner in three independent trials. Mean of quantification value suggests the mean of quantitative value (normalized total spectra) calculated by Scaffold 5 software, the value outside the parenthesis stands for HA-tagged TBP55 sample while the value inside the parenthesis stands for mock control. The order is sorted by frequency of identification firstly, and the mean of quantitative value secondly.
