id1 (MAIZE) review notes
Session 1 (2026-10-28)
just fetch-gene MAIZE id1 resolved UniProt O65215 (GeneID 541693), as requested. 9 GOA rows:
2 IBA (DNA-binding TF activity, nucleus), 7 IEA (EnsemblPlants Compara projection from
rice EHD2/OsId1 B1B534, plus one ARBA-combined row).
- No experimental GOA rows exist for maize ID1, although experimental papers do:
Kozaki 2004 PMID:15020707 (full text; in vitro DNA binding), Wong & Colasanti 2007
PMID:17307745 (abstract; nuclear immunolocalization). Added NEW IDA rows for
sequence-specific DNA binding and nucleus from these.
- Photoperiodism rows (LD and SD flowering) come from rice. Maize ID1 is the
autonomous-pathway regulator; its expression is photoperiod insensitive PMID:17307745,
and rice OsId1 acts "regardless of photoperiod" PMID:18774969. Photoperiodism
("change ... as a result of detection of ... a period of light or dark of a given length")
is therefore an over-annotation; marked MARK_AS_OVER_ANNOTATED, not REMOVE (IEA from an
experimental rice annotation; no maize experiment refutes it in tropical maize).
- Positive regulation of transcription: activation shown only for rice OsId1 in yeast
PMID:18774969; maize ZCN8 regulation is probably indirect PMID:21730358. Kept as
non-core.
- Rejected NEW BP terms: no 'positive regulation of flower development' etc.; mutant
phenotype alone. GO:0048510 already covers the role.
- Lazakis 2011 PMID:21730358 read in full: id1 upstream of ZCN8; ZCN8 is unlikely a
direct target.
