MAPR3 is located in the ER, cytoplasm, and possibly other endomembrane compartments.. The green and red fluorescence were observed when 35S::MAPR3–GFP and various organ markers tagged with RFP or mCherry were co-expressed in tobacco leaf cells. (A) MAPR3–GFP co-localized with the ER marker RFP–HDEL. (B–D) MAPR3–GFP partially co-localized with the early endosome marker RAB-A2a–mCherry (B),the late endosome marker SYP22–mCherry (C), and the vacular marker DELTA-TIP1–mCherry (D). Thin arrows indicate merged signals.
