Estrogen receptor signaling pathway module

Estrogen receptors act as ligand-regulated nuclear receptors and signaling scaffolds, recruiting co-regulators to control chromatin, transcription, and cell-type-specific hormone responses.

Estrogen receptor signaling pathway Falcon module review
Falcon/Edison module review generated 2026-06-28 is linked as supporting evidence for module boundaries, core mechanism, variation, constraints, and failure modes; open questions in that report require manual review before promotion to curated knowledge gaps.
GO:0030520
estrogen receptor signaling pathway
The module is grounded in the GO biological process term for estrogen receptor signaling pathway.

Curated compact signaling-pathway module generated from verified UniProt exemplar accessions and local PAINT IBD rows. PTN anchors are included only when the exemplar accession appears in an IBD seed row in interpro/panther; roles without local PAINT seeds remain grounded by verified UniProt exemplar accessions. No local PAINT IBD seed rows were found for the verified exemplar accessions in this module, so no ancestral_nodes are asserted. Falcon integration (2026-06-28): Falcon findings are linked as evidence and family-level support. Automatically extracted open-question headings were intentionally not retained as knowledge_gap entries because they were not manually curated. Machine-generated Falcon citations remain curation support and are not manually adjudicated here.
