Relative phosphorylation for representative phosphopeptides in each defined cluster. Cluster I, solute carrier family protein Slc6 (MGG_05433); cluster II, Sec73 (MGG_06905); cluster III, Yak1 (MGG_06399); cluster IV, Apt2 (MGG_07012), and cluster V, chitin synthase 6 (CH6) (MGG_13013). Data shown in (B)-(D) are based on 3 biological replicates. See alsoFigure S1.
