CC   -!- FUNCTION: Mediates the regulatory switch from transcription to RNA
CC       replication. Acts late in infection by inhibiting viral transcription
CC       and up-regulating RNA replication. Inhibition of transcription by
CC       protein M2-2 requires phosphorylation of the phosphoprotein.
CC       {ECO:0000250|UniProtKB:P88812}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250|UniProtKB:P88812}.
CC   -!- SIMILARITY: Belongs to the orthopneumovirus M2-2 protein family.
CC       {ECO:0000305}.
