Description: In contrast, mRNAs encoding Cox6p, Cox5a, Aac1p, and Mir1p are found enriched in free cytoplasmic polysome fractions. Transcripts coding for Atm1p, Cox10p, Tim44p, Atp2p, and Cot1p are exclusively localized to mitochondrion-bound polysomes, while mRNAs encoding Cox6p, Cox5ap, Aac1p, and Mir1p are enriched in free cytoplasmic polysomes. The third family mRNAs were those predominantly associated with free cytoplasmic polysomes (Fig. ?(Fig.1A,1A, lanes F-P), such as COX6, COX5a, AAC1, and MIR1.
