Module context: dmel_mitochondrial_degradosome (PNPase with Suv3).
Deep research: the first falcon attempt failed; a retry produced PNPase-deep-research-falcon.md after the review was drafted. It agrees with this review: mitochondrial localization (TOM20 colocalization; enrichment in larval mitochondrial fractions), mitochondrial mRNA/antisense decay and dsRNA accumulation on loss; it reports no cytosolic function for the enzyme itself.
Decisions: activity, mitochondrial RNA/mRNA catabolism, mitochondrion/matrix and
degradosome accepted. Over-annotations: IBA mitochondrial RNA 3'-end processing (fly
processing is PNPase-independent), IBA cytosol and ARBA cytoplasm (bacterial-family
compartment).
