{"rfam": {"acc": "RF00489", "id": "ctRNA_p42d", "description": "ctRNA", "comment": "This family represents a group of ctRNAs (or counter-transcribed RNAs) from p42d and related plasmids. ctRNAs are small, highly structured, antisense sequences which are involved in negative regulation. Members of this family are known to bind to the mRNA of repC causing translational repression [1]. This model contains the predicted stem-loop structure followed by a U-rich tract which is proposed to act as a Rho-independent transcriptional terminator.", "curation": {"author": "Moxon SJ", "seed_source": "PMID:15554980", "num_seed": 10, "num_full": 245, "num_species": 136, "type": "Gene; antisense;", "structure_source": "Published; PMID:15554980"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 26.28 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 50.0, "trusted": 50.0, "noise": 49.9}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": null, "id": null}}}
