Both MRP1/2 and RBP16 are required for maintenance of COI, ND4, and edited MURF2 RNA levels in PF cells, and they act in the same process. (A) The same RNA populations were analyzed as in Fig. 2A. qRT-PCR was performed for COI, ND4, preedited MURF2, and edited MURF2 RNAs. (B) The same RNA populations were analyzed as in Fig. 2B. The error bars indicate standard deviations.
