Smk1 is autophosphorylated on residue Y209. (A) Extracts from wild-type SMK1-HA (upper panel) and smk1-K69R-HA (lower panel) strains prepared at the indicated times after transfer to sporulation medium were analyzed by electrophoresis through Phos-tag gels and immunoblotting using an HA antibody. (B) Samples from an smk1Δ/smk1Δ strain harboring the indicated low-copy-number (CEN-based) Smk1-HA plasmids were harvested 9.5 h after meiotic induction and assayed as described for panel A. (C) SMK1/SMK1-HA (WT/WT-HA), smk1-K169R/smk1-K169R-HA (KR/KR-HA), and SMK1/smk1-K169R-HA (WT/KR-HA) cells were harvested 9.5 h following meiotic induction and assayed as described for panel A.
