{"rfam": {"acc": "RF00426", "id": "SCARNA15", "description": "Small Cajal body specific RNA 15", "comment": "scaRNAs are a specific class of small nuclear RNAs which localise to the Cajal bodies and guide the modification of RNA polymerase II transcribed spliceosomal RNAs U1, U2, U4, U5 and U12 [1]. ACA45 belongs to the H/ACA box class of guide RNAs as it has the predicted hairpin-hinge-hairpin-tail structure, the conserved H/ACA-box motifs and is found associated with GAR1 [2]. ACA45 is predicted to guide the pseudouridylation of residue U37 of the U2 spliceosomal snRNA [2].", "curation": {"author": "Moxon SJ, Daub J", "seed_source": "Moxon SJ, INFERNAL", "num_seed": 22, "num_full": 635, "num_species": 528, "type": "Gene; snRNA; snoRNA; scaRNA;", "structure_source": "Predicted; RNAFOLD; Moxon SJ"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 21.00 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 65.0, "trusted": 65.0, "noise": 64.7}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": "CL00019", "id": "SCARNA4"}}}
