SWN (SWINGER / EZA1) curation notes

Session 2026-10-06 (vernalization_flc_silencing module follow-up)

• Q9ZSM8, At4g02020. The UniProt primary name is EZA1; gene_symbol is SWN (TAIR name; a UniProt synonym), matching the folder.
• PHD-PRC2 E(z) subunit: PMID:18854416.
• Redundancy with MEA in the gametophyte: PMID:16924116
• H3K27me3 deposition: PMID:35394700.

Decisions

• Plasmodesma HDA (PD proteome) -> REMOVE. This nuclear PRC2 enzyme is very likely a contaminant: PMID:21533090.
• Protein-binding rows -> REMOVE. NEW ESC/E(Z) complex.
