View original ARBA rule on UniProt
Assigns GO:0120114 Sm-like protein family complex through 27 alternative condition sets of InterPro and CATH FunFam signatures, some with a taxon. The sets cover Sm and Lsm proteins and other protein components of the U1, U2, U5, U6, U7 and U11/U12 snRNPs.
Condition-set counts describe the sets recorded in this review, which may omit the full rule.
No domain overlap table is shown: the cached overlap analysis for this version of the review is not available.
Run just analyze-rule ARBA00027169 and re-render to add it.
All 27 live condition sets were examined. Every set matches Swiss-Prot entries, and in each at least one matched entry carries GO:0120114 or a descendant with experimental evidence; no matched Swiss-Prot entry lacks the term. Spliceosomal snRNPs are subclasses of GO:0120114 (GO:0030532 small nuclear ribonucleoprotein complex is_a GO:0120114), so snRNP proteins without an Sm fold, such as SF3B1, PRPF8, BRR2 and Snu114, are correctly covered.
Each set selects snRNP or Lsm-complex components with experimental cellular-component annotation under the rule's term. Narrow taxon conditions on some sets (for example Rattus in set 15) limit coverage but do not make the annotation wrong.
Per-set receipts are in rule.condition_sets[].notes. Accessions listed are Swiss-Prot matches with experimental evidence for GO:0120114 or a descendant in QuickGO (first 40).

Curated experimental GO annotations on matched Swiss-Prot entries are listed per set in rule.condition_sets[].notes (QuickGO, November 2026), for example P36048 (SN114_YEAST) GO:0005682 U5 snRNP IDA PMID:11720284 (set 13) and SMD3_YEAST GO:0005682 IDA PMID:11720284 (set 14).
The matched proteins are annotated to different descendants of GO:0120114 (for example GO:0005682 U5 snRNP, GO:0005685 U1 snRNP, GO:0005686 U2 snRNP, GO:0005688 U6 snRNP), so GO:0120114 is the common term across the sets. A per-set snRNP term would be more specific.

review_summary: All 27 live condition sets were examined. Every set matches Swiss-Prot entries, and in
each at least one matched entry carries GO:0120114 or a descendant with experimental evidence; no matched
Swiss-Prot entry lacks the term. Spliceosomal snRNPs are subclasses of GO:0120114 (GO:0030532 small
nuclear ribonucleoprotein complex is_a GO:0120114), so snRNP proteins without an Sm fold, such as SF3B1,
PRPF8, BRR2 and Snu114, are correctly covered.
action: ACCEPT
action_rationale: Each set selects snRNP or Lsm-complex components with experimental cellular-component
annotation under the rule's term. Narrow taxon conditions on some sets (for example Rattus in set 15)
limit coverage but do not make the annotation wrong.
literature_support:
assessment: STRONG
notes: Curated experimental GO annotations on matched Swiss-Prot entries are listed per set in rule.condition_sets[].notes
(QuickGO, November 2026), for example P36048 (SN114_YEAST) GO:0005682 U5 snRNP IDA PMID:11720284 (set
13) and SMD3_YEAST GO:0005682 IDA PMID:11720284 (set 14).
go_specificity:
assessment: APPROPRIATE
notes: The matched proteins are annotated to different descendants of GO:0120114 (for example GO:0005682
U5 snRNP, GO:0005685 U1 snRNP, GO:0005686 U2 snRNP, GO:0005688 U6 snRNP), so GO:0120114 is the common
term across the sets. A per-set snRNP term would be more specific.

corrections:
- date: '2026-11-10'
withdrawn_claim: Condition set 13 wrongly includes a translation elongation factor and should be removed.
correction: Set 13 is a conjunction of two FunFams with Fungi. Its Swiss-Prot matches are Snu114 and
its fission yeast ortholog, the EF-2-like GTPase of the U5 snRNP.

evidence:
- QuickGO ancestors of GO:0005682 U5 snRNP include GO:0030532 small nuclear ribonucleoprotein complex
and GO:0120114 Sm-like protein family complex
- date: '2026-11-10'
withdrawn_claim: GO:0071004 "U2-type spliceosomal complex" would be a more specific term.
correction: GO:0071004 is U2-type prespliceosome and is not a descendant of GO:0120114.
error_type: WRONG_IDENTIFIER_MEANING
evidence:
- 'QuickGO: GO:0071004 U2-type prespliceosome; its ancestors do not include GO:0120114'
- date: '2026-11-10'
withdrawn_claim: 28 condition sets exceed the 12 condition limit for analysis, which justifies deprecation.
correction: The limit is the default of this repository's overlap-analysis tool, not a property of the
rule. All 27 live sets were checked individually.
error_type: SIZE_AS_EVIDENCE
evidence:
- 'src/ai_gene_review/etl/rule_analysis.py: max_condition_sets: int = 12'
- Per-set evidence in rule.condition_sets[].notes
- date: '2026-11-10'
withdrawn_claim: Taxonomic scope is inconsistent (Eukaryota to Rattus), so the rule may annotate proteins
inappropriately.
correction: A narrow taxon condition makes a set fire on fewer proteins; it cannot cause a wrong annotation.
error_type: TAXON_MISREAD
evidence:
- 'Set 15 (Rattus): Swiss-Prot matches RSMB_RAT and RSMN_RAT, both with GO:0120114 descendants (rule.condition_sets[14].notes)'
