    review_notes: Substantive computational synthesis directly addressing the GO:0030030 prediction. The
      report's broad WDPCP/CPLANE orthology conclusion is independently corroborated by the cached
      sequence-comparison evidence, and its orthology-only and term-specificity caveats were retained.
  findings:
  - statement: OpenScientist supported GO:0030030 as a broad horse WDPCP process annotation via conserved
      CPLANE/ciliogenesis and planar-polarity biology, with curation caveats on term breadth and orthology-only
      evidence.
    supporting_text: GO:0030030 is therefore biologically justified for the horse protein. The two curation
      caveats are that the term is generic (specific children such as cilium assembly and establishment
      of planar polarity are better supported) and that all functional evidence is transferred by orthology
      to an unreviewed TrEMBL record, so an **ISS/ISO** evidence code is appropriate rather than an experimental
      one.

    summary: Wdpcp loss disrupts cilia and actin-based protrusive behavior. Conservation of the WD40/alpha-solenoid
      scaffold supports the broad cell-projection-organization prediction; the OpenScientist 83% identity
      estimate and cached 88.1% identity over 704 paired residues reflect different alignment scopes but
      the same WDPCP orthology. The N-terminal length difference resembles known human–mouse variation;
      a short lipid-binding-tail deletion leaves affinity, not this entire broad role, unresolved. More
      specific children such as cilium assembly and establishment of planar polarity are better supported,
      and any horse assignment should use ISS/ISO rather than experimental evidence.
