Updated project metadata. The fresh cells as described above were harvested and lysed in buffer containing 8 M Urea, 50 mM NH4HCO3 and 5 mM IAA. The total cell lysates were centrifuged with 12,000 g for 10 min at 4 degrees Celsius to remove cell debris, and 1.5 mg proteins for each cell line were followed by sequential in-solution protein digestion by Lys-C and trypsin at 37 degrees Celsius, respectively. The tryptic peptides were cleaned by C18 Sep-Pak column (Waters UK Ltd, Manchester, UK).</br></br>The mass spectrometer used in this dataset was Q-Exactive. The dataset was produced with two technical replicates and 24 fractions per repeat. The database searching procedure was achieved using Mascot v2.3. The database is Swiss-prot (release 2013 -6).
