erg11 (SPAC13A11.02c, UniProt Q09736) notes

Module: ergosterol_biosynthesis (CYP51); S. cerevisiae ortholog ERG11 (P10614). Fetch verified: Q09736 (CP51_SCHPO).
Naming: UniProt mentions "erg11/cyp1"; the protein is CYP51 (Cyp51A1 in Hughes et al. 2007).

Evidence

• Essential lanosterol 14alpha-demethylase PMID:27585850; PMID:27585850.
• Dap1 binds and activates it PMID:17276356.
• Cortical ER + nuclear envelope PMID:37939137; Lem2 interactor PMID:36799444.

Curation decisions

• protein binding (Dap1) REMOVE as uninformative; interaction not disputed.
• monooxygenase / paired-donor oxidoreductase IEA MODIFY -> GO:0008398; membrane -> ER membrane.
• UniProt PANTHER xref is PTHR24304:SF2 (labelled 24-hydroxycholesterol 7-alpha-hydroxylase) - a PANTHER labelling quirk worth noting for the module's CYP51 family descriptor.
