{"rfam": {"acc": "RF00182", "id": "Corona_package", "description": "Coronavirus packaging signal", "comment": "This family represents a predicted coronavirus packaging signal. Within a virally infected cell, viral genome and viral proteins specifically and selectively unite into progeny viruses. This process is called packaging and is vital for viral replication. Viral RNA containing a packaging signal allows the sequence to be efficiently packaged into the virion. The family was reviewed in 2020 to ensure that all 4 AGC/GUAAU elements were present in SS_cons and to include more sequences in the seed. Previously this family was based on PMID:12791173 which incorrectly claimed that this structure is found in SARS-CoV.", "curation": {"author": "Moxon SJ, Petrov AI", "seed_source": "PMID:17428856", "num_seed": 6, "num_full": 10, "num_species": 12, "type": "Cis-reg;", "structure_source": "Published; PMID:17428856"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 30.00 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 80.0, "trusted": 82.5, "noise": 49.1}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": null, "id": null}}}
