Sporulation was induced as described earlier and 50 ml of cells at various time points were pelleted. Protein was isolated from cells pellets with FA-1 lysis buffer (50 mM HEPES pH 7.5, 150 mM NaCl, 1 mM EDTA, 1% Triton X-100, 0.1% Sodium Deoxycholate, 1 mM PMSF and protease inhibitors) using bead-beating methods. Immunoprecipitation was performed with anti-SNF2 antibody (yN-20, Santa Cruz, 10 μl per IP) and γ-G sepharose beads and washed with the lysis buffer. Western blots were performed as described above.

Protein extraction and western blot analysis was carried out as previously described [6 (link)] using a phospho-p38 MAPK (Thr180/Tyr182) antibody to detect the SakA phosphorylated form, a phospho-p44/42 MAPK (Erk1/2) (Thr202/Tyr204) antibody to detect the MpkA phosphorylated form (Cell Signaling Technology), and a γ-tubulin antibody as a reference (yN-20) (Santa Cruz biotechnology, Inc.). Every experiment was repeated at least three times, using independent biological replicates. Additional information is reported in S1 Text.

Beauvericin Modulates Sch9 and Ypk1 Phosphorylation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The yor1Δ strain was grown overnight in YEPD at 30°C, diluted to an OD600 of 0.1, and 5 ml of culture was treated with appropriate vehicle (methanol) or drug (5 μg/ml beauvericin) at appropriate time points. All samples were collected after 4 hours. Cell growth was stopped by adding 100 % w/v TCA to a final concentration of 6 % v/v. After harvesting, cell pellets were processed for western blotting as previously described56 (link). A Licor Odyssey Scanner was used to detect phosphorylated Sch9 (P-Sch9T758), phosphorylated Ypk1 (P-Ypk1T662), total Sch9, and total Ypk1. Monoclonal antibodies against P-Sch9, P-Ypk1, and total Sch9 were used, and a commercially available antibody from Santa Cruz (yN-20) was used for total Ypk1 detection. Secondary IRDye antibodies from Li-Cor Biosciences were used for primary antibody detection.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
