Discussions
- CURATION_TODO (OPEN): Resolve exact source-neutral family groundings for the Rpd3L-Expanded constituents. GO:0070210 defines 19 budding-yeast proteins as Rpd3L-Expanded complex constituents. Exact cross-eukaryotic InterPro, Pfam, NCBIfam or UniProt family boundaries for these Rpd3L-Expanded subunit classes need narrower curation before these component labels can be grounded.
