Cell preparation for western blot: cells were harvested by centrifugation (4000 x g , 6 min, 4 °C). Supernatant was discarded and cells were resuspended in 500 μl cold TCA buffer (20 mM Tris, pH 8, 50 mM ammonium acetate, 2 mM EDTA, 1 tablet/10 ml of Complete Mini Protease inhibitor cocktail with EDTA (Roche Diagnostics GmbH)). 500 μl 0.5 mm Zirconia/Silica Beads (BioSpec Products, Inc. 11079105z) and 500 μl cold 20 % TCA was added. Samples were vigorously vortexed twice for 30 sec (kept on ice in between). 750 μl from the liquid phase was transferred into a fresh Eppendorf tube. Samples were centrifuged for 10 min (20000 x g, 4 °C). The pellet was resuspended in 300 μl TCA-Laemmli buffer and boiled for 10 min at 100 °C.

10 μl total protein from 9.25 x 107 cells of Saccharomyces cerevisiae extracted with 20% TCA as described below were separated on 20% SDS-PAGE and blotted 1.5h (0.5 A) to a nitrocellulose membrane (Whatman PROTRAN BA 85, 0.45 μm). Blots were blocked with 5% non-fat dry milk in TBST for 1.5h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 5 000 overnight at 4C° with agitation. The antibody solution was decanted and the blot was washed 3 times for 10 min in TBST at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated from Agrisera, (AS09 602) diluted to 1:50 000 for 1h at RT with agitation. The blot was washed as above and developed for 3 min with SuperSignal West Pico Stable Solution (1856135 Thermo Scientific) and SuperSignal West Pico Luminol/Enhancer Solution (1856136 Thermo Scientific) mixed 1:1 rate according to the manufacturers instructions. Exposure time was 30 seconds.
