The following antibodies were used: MYC (9B11, Cell Signaling), CHK2 (BD Biosciences), hRAD50 (Novus, NB100-154SS), hUBR5 (EDD) (Santa Cruz, sc-9562), Flag (Sigma, F7425) or HA (Covance, 16B12), γH2AX (Millipore, JBW301), 53BP1 (Novus, NB 100-304), GFP (Invitrogen, A6455), BRCA1 (a gift from X. Yu), RNF168 (a gift from D. Durocher) and FK2 (Millipore, 04-263).
For immunoprecipitation the following antibodies were used: MYC (9B11, Cell Signaling) and Flag M2 affinity gel (Sigma, A2220). Quantification of immunofluorescence experiments was performed by counting at least 200 cells per condition. Data from three independent experiments were used to calculate median value and standard deviation.
shRNA
pLKO lentiviral vectors were used to express shRNAs directed against the following targeting sequences: 5′-GCTCAGTATTTACCAAGAATT-3′ (Brcc3), 5′-GTCCATCCAAGTGGAGTACAT-3′ (Otub1), 5′-CCCATTCAGTATCCTGGCTT-3′ (Rap80) and 5′-AACCAGATGTCTGTACTAAGG-3′ (Brca1).
Purification of protein interacting with the iDDR region
HEK293 cells were transfected with Flag-tagged TRF1 or Flag-tagged TRF1iDDR. Cells were lysed (50 mM Tris–HCl, pH 7.5, 150 mM NaCl, 1 mM EDTA buffer, 0.5% Triton X-100) and immunopurified with anti-Flag agarose resin (Sigma). After washing, proteins were eluted by competition with Flag peptide (Sigma). For mass spectrometry analysis samples were denatured, reduced and alkylated before an overnight digestion with trypsin. 展开
