{"rfam": {"acc": "RF00093", "id": "SNORD18", "description": "Small nucleolar RNA SNORD18", "comment": "U18 is a member of the C/D class of snoRNA which contain the C (UGAUGA) and D (CUGA) box motifs. It is encoded in introns of ribosomal protein L1 in Xenopus and human, and in introns of elongation factor 1 beta in yeast. Related snoRNAs in Arabidopsis and rice have been named R63 and Z106 respectively. Factors involved in the processing of the intronic snoRNA have recently been elucidated [2].", "curation": {"author": "Griffiths-Jones SR", "seed_source": "Griffiths-Jones SR", "num_seed": 16, "num_full": 2622, "num_species": 960, "type": "Gene; snRNA; snoRNA; CD-box;", "structure_source": "Predicted; PFOLD; Griffiths-Jones SR"}, "cm": {"build_command": "cmbuild -F CM SEED", "calibrate_command": "cmcalibrate --mpi CM", "search_command": "cmsearch --cpu 4 --verbose --nohmmonly -T 22.00 -Z 2958934 CM SEQDB", "cutoffs": {"gathering": 41.0, "trusted": 41.0, "noise": 40.9}}, "release": {"date": "2026-01-16", "number": "15.1"}, "clan": {"acc": "CL00047", "id": "SNORD18"}}}
