CST interacts with ShieldinAuthor Manuscripta, Immunoprecipitation of individual mouse CST subunits or the three subunit complex (every subunit bearing a Myc-tag) with Flag-tagged mouse Shld1 co-expressed in 293T cells. Flag-tagged POT1b and POT1a serve as optimistic and adverse controls for CST binding, respectively. Representative of two experiments. b, Two-hybrid analysis of CST-Shieldin interaction. Yeast cultures were grown overnight in synthetic total medium lacking tryptophan and leucine to a density of 5107 cells/ml. Serial 10-fold dilutions have been generated and four ul of each dilution was spotted on synthetic total media lacking theNature.

Impact of CST and Pol on PARPi treatment of BRCA1-deficient cellsAuthor Manuscripta-f, Immunoblots around the MEFs used in Fig. 4a-e to confirm the absence of deleted proteins and efficacy of your shRNAs. Reduction in Stn1 expression is used as a proxy for the efficacy of your Ctc1 shRNA considering the fact that no antibody to mouse Ctc1 is readily available. Each immunoblot is representative of three experiments. g, Immunoblots for BRCA1 and Stn1 within the cells utilized in Fig. 4f.
