Conservative subtype-level sketch linking a DefenseFinder CARD_NLR_GasderMIN locus to CARD-like gasdermin anti-phage defense and CARD-NLR GasderMIN system possession.

NONMECHANISTIC · The graph captures the CARD_NLR_GasderMIN subtype at DefenseFinder rule-row level without asserting the exact phage trigger, native host breadth, CARD-to-gasdermin activation sequence, bGSDM cleavage route, or whether every DefenseFinder CARD_NLR_GasderMIN prediction is a complete experimentally active locus.

Attached to causal_graphs#card_nlr_gasdermin_locus_subtype_defense

Wein et al. support CARD-like anti-phage gasdermin defense, the pinned DefenseFinder HMM inventory supports GasderMIN__bGSDM as a bGSDM profile, and the pinned DefenseFinder rules table supports CARD_NLR_GasderMIN as a rule-row subtype requiring GasderMIN__bGSDM. This first-pass record leaves exact phage triggers, native hosts, CARD-to-gasdermin activation, bGSDM proteolysis route, and profile-to-activity criteria unresolved.

Curation history

2026-10-02T21:05:00Z · MINTED_TRAITMECH_ID · codex
Minted CARD-NLR GasderMIN system as a DOI- and DefenseFinder-backed GENOMICS TraitRecord under the CARD-NLR system parent after an ignored-and-hidden duplicate review found no exact live TraitMech, METPO, history, or prior proposal record for the target local ID, placeholder METPO ID, proposal cohort, record slug, or human label; existing CARD_NLR_GasderMIN mentions were scoped to CARD-NLR parent or GasderMIN evidence, not an exact child TraitRecord, and the replacement placeholder is reserved in proposals/metpo_traitmech_v432.
2026-10-02T21:05:02Z · REVIEW_CANONICAL_EXAMPLE_EVIDENCE_GAP · codex
Reviewed CARD-NLR GasderMIN system during initial curation and left canonical_examples empty because Wein et al. and the pinned DefenseFinder tables support CARD-like anti-phage gasdermin defense and the CARD_NLR_GasderMIN rule row but not an accession-backed native microbial taxon exemplar tied to CARD_NLR_GasderMIN profiles and experimentally verified endogenous activity. No paid research was used.
