Figure 2. The PH-GRAM Domain and Phosphatase Activity Are Required for Ymr1 Localization to the PAS.
(A) WT cells expressing RFP-Ape1 and Ymr1-GFP (ECY202) were incubated with rapamycin for 3 hr before collecting images.
(B) Cells expressing RFP-Ape1 and Sjl3-GFP (AVY070) were treated and imaged as in (A).
(C) The ymr1Δ RFP-Ape1 (ECY207) strain carrying integrated pYMR1GFP(406) (Ymr1-GFP), pNΔYMR1GFP(406) (NΔYmr1-GFP), or pYMR1C397SGFP(406) (Ymr1C397S-GFP) were starved for 3 hr in SD-N medium before imaging. Arrows highlight colocalization. DIC, differential interference contrast.
(D) Quantification of the degree of RFP-Ape1 colocalization with the GFP-tagged proteins in the samples imaged in (C). The graphs represent the average of two experiments ± SEM.
Scale bars represent 5 μm. See also Figure S2.
