Mass spectrometry of PtGtsf1 interacted proteins in Paramecium tetraurelia

PtGtsf1 was fused with FlagHA and induced to express in Paramecium tetraurelia. The interacted proteins of PtGtsf1 was obtained by immunoprecipitation with anti-HA antibody, followed with mass spectrometry to identify the proteins. Meanwhile, FlagHA without PtGtsf1 was expressed in Paramecium tetraurelia as control and was performed with same procedures as PtGtsf1-FlagHA. By comparing the enrichment of proteins in PtGtsf1-FlagHA and control, the interacted proteins of PtGtsf1 in Paramecium tetraurelia were identified.
