Phosphorylation of Ser-114 on Atg32 is critically important for the Atg11–Atg32 interaction. (A, B) Yeast two-hybrid analysis between Atg11 and the indicated Atg32 mutants. (C) The atg11Δ atg32Δ strains expressing PA-tagged Atg32WT, PA-tagged Atg32S114A, or PA-tagged Atg32S114T and HA-tagged Atg11 under the control of the CUP1 promoter were grown in SMD medium until the mid–log phase and then starved in SD-N for 1 h. PA-Atg32 was precipitated using IgG–Sepharose from cell lysates. Top two, an immunoblot of total-cell lysates. Bottom two, the IgG precipitates, which were probed with anti-HA and anti-PA antibodies.
