Mutational analysis of Arabidopsis chloroplast
polynucleotide phosphorylase reveals roles for both RNase PH core domains in polyadenylation, RNA 3 «- end maturation and intron degradation
The report (1)-- from a group led by UCLA's Dr. Michael Teitell, and including graduate student Carla Koehler, Newcastle University's Dr. Robert Lightowlers, and others — identified and provided initial characterization of
polynucleotide phosphorylase (PNPase) as a mammalian - specific system for the mitochondrial import of nuclear - encoded RNA.
