Fig. 2. STR and Smc5/6 prevent joint molecule accumulation at stalled replication forks and termination regions.

Fig. 2

a Schematic representation of replication intermediates arising at termination regions as observed by 2D gel electrophoresis. The migration pattern of different replication intermediates referred to in the text is illustrated. b Schematic representation of the NPS302/TER302 region analysed by 2D gel electrophoresis. c Visualization of replication intermediates by 2D gel electrophoresis from cells of the indicated genotype synchronously released from G1 in media containing 200 mM HU, as well as Auxin (Aux) and Tetracycline (Tc). FACS profiles indicated on the right show cell cycle progression. Sgs1 and Top3 tagged with HA were depleted with Auxin and Tetracycline as indicated by Western blots. Pgk1 was used as loading control. Joint molecules accumulating on the X-arc are indicated by red arrows. The experiment was performed reproducibly twice. See also Supplementary Figs. 3 and 4.
