  Curated PN-to-GO mappings for ER proteostasis, including glycoproteostasis, ERAD, and transport.
subject_curations:

    post-translational protein targeting to endoplasmic reticulum membrane.
    Propagating the broad parent protein-transport term would add less precise

  notes: >-
    ERP27 and ERP29 are excluded from GO:0003756 propagation after gene-level
    review (proteostasis batch 5). Both are PDI-family ER-resident proteins
    that LACK the redox-active thioredoxin CXXC active-site motif and therefore
    have no protein-disulfide-isomerase catalytic activity: ERP27 is a
    non-catalytic substrate-binding partner that presents unfolded clients to
    PDIA3/ERp57, and ERP29 is a non-catalytic homodimeric escort/chaperone.
    Both reviews carry NOT|protein-disulfide-isomerase-activity annotations.
    ERO1A and ERO1B are also excluded from this group-level GO:0003756
    propagation: they are FAD-dependent sulfhydryl OXIDASES that reoxidize PDI,
    not isomerases (their gene reviews flag the PDI/reductase terms as
    over-annotations). They retain the corrected molecular function GO:0016971
    (flavin-dependent sulfhydryl oxidase activity) via the child "Protein
    disulfide isomerase reoxidation" type node; the parent PDI-activity term
    must not propagate to them. Inheriting GO:0003756 from this group would
    over-annotate these escort chaperones and oxidases; their genuine roles are
    captured at the gene level. The catalytic isomerase members (e.g. P4HB/PDI,
    PDIA3, PDIA4, PDIA6) retain the mapping, and DNAJC10/ERdj5 (a thioredoxin-
    family reductase) is also retained.

  rationale: >-
    This PN group captures the ER N-glycosylation machinery that installs and
    processes N-linked glycans during proteostasis. GO protein N-linked
    glycosylation is the best current propagation target in the local cache.

      chaperone
  notes: >-
    The Lectin chaperone type (calnexin/calreticulin family: CANX, CALR, CLGN,
    CALR3) is excluded after gene-level review. These members bind
    monoglucosylated N-glycans as molecular chaperones but do not catalyze
    N-linked glycosylation, so inheriting the catalytic process term
    GO:0006487 from this group overstates their function. Gene reviews of the
    testis lectin chaperones CLGN (calmegin) and CALR3 (calreticulin-3)
    confirmed protein folding / chaperone roles with no glycosyltransferase
    activity. The enzymatic members of this group (oligosaccharyltransferase
    complex components) retain the GO:0006487 propagation via the narrower
    type-level mappings.

    label: collagen biosynthetic process

    pathway context.

  notes: >-
    Confirmed by gene-level review (proteostasis batch 5): SERPINH1/HSP47 is a
    collagen-specific ER molecular chaperone, PPIB/cyclophilin B is the ER
    peptidyl-prolyl isomerase that catalyzes collagen prolyl isomerization (with
    the P3H1/CRTAP complex), and P4HB/PDI serves as the structural beta-subunit
    of prolyl 4-hydroxylase. All three support the shared collagen-biogenesis
    process context at propagation scope. (Note that the substrate-specific
    process term is the appropriate shared mapping; member-specific molecular
    functions such as PPIase activity, collagen binding, and PDI activity are
    captured at the gene level.)

    degradation
  subject_level: group
  curation_status: mapped
  target_term:
    id: GO:0036503
    label: ERAD pathway
  mapping_scope: exact
  rationale: >-
    The PN group "ER associated degradation" is a direct lexical and
    biological match to the GO ERAD pathway term. The additional branch and
    class context disambiguates the source string from any broader degradation
    language.

  target_term:

    label: post-translational protein targeting to endoplasmic reticulum membrane
  mapping_scope: ok_for_propagation_to_go
  rationale: >-
    The PN GET-pathway group covers machinery for post-translational delivery
    of tail-anchored membrane proteins to the ER. GO does not model the GET
    pathway directly in the local cache, and the closest supported process
    term is post-translational targeting to the ER membrane.

  - file:human/SGTA/SGTA-ai-review.yaml
  notes: >-
    Confirmed by gene-level review (proteostasis batch 5): SGTA is a small
    glutamine-rich TPR cochaperone that acts in the BAG6/TRC40-GET pathway,
    functioning as a molecular adaptor in the targeting and quality control of
    tail-anchored membrane proteins for insertion into the ER membrane,
    consistent with this post-translational ER-targeting process mapping.

    SRP receptor subunits participate in docking the SRP-ribosome complex to

  mapping_scope: ok_for_propagation_to_go
  rationale: >-
    This PN group captures core signal-recognition-particle machinery used to
    direct translating ribosome-nascent chain complexes to the ER membrane.
    The group is machinery-centric rather than process-equivalent, so it
    propagates to the GO targeting process.

  mapping_scope: ok_for_propagation_to_go
  rationale: >-
    This PN group covers ER transmembrane-protein insertion/import systems
    such as EMC- and PAT-related pathways. The local GO cache does not expose
    an ER-specific matching term, so the broader intracellular-organelle
    transmembrane-import process is the best supported propagation target.

    Gene-level review of CNPY3 (PRAT4A) confirmed this propagation: it is an

    label: flavin-dependent sulfhydryl oxidase activity
  mapping_scope: ok_for_propagation_to_go
  rationale: >-
    Corrected after gene-level review (proteostasis batch 5). This PN type is
    the ERO1 "PDI reoxidation" step, whose members (ERO1A/ERO1L, ERO1B/ERO1LB)
    are FAD-dependent sulfhydryl OXIDASES that reoxidize PDI to regenerate its
    active site — they do not themselves catalyze protein disulfide isomerization.
    The previous target GO:0003756 (protein disulfide isomerase activity) was
    incorrect for this node and would mislabel the oxidases as isomerases (both
    ERO1A and ERO1B reviews mark the protein-disulfide reductase/isomerase terms
    as over-annotations). The correct shared molecular function is
    GO:0016971 flavin-dependent sulfhydryl oxidase activity, which both genes
    carry with experimental (EXP) evidence in GOA.

    label: ERAD pathway
  mapping_scope: ok_for_propagation_to_go
  rationale: >-
    This PN type captures the VCP/p97-dependent retrotranslocation machinery
    used in ERAD. It is not a separate process from ERAD, but a core
    mechanistic subsystem within it.

  mapping_scope: ok_for_propagation_to_go
  rationale: >-
    In `4.3.11`, the earlier retrograde-transport bucket has been folded into
    ER-Golgi trafficking and now specifically denotes COPI/KDEL-style
    retrograde trafficking from Golgi back to ER. The correct GO target is
    therefore retrograde vesicle-mediated transport, Golgi to endoplasmic
    reticulum rather than ER-to-cytosol retrotranslocation.

    trimming used in glycoprotein quality control and ERAD triage. That is
    close enough for propagation to the GO mannose-trimming-in-ERAD process,
    but the PN subtype is framed as a proteostasis step rather than a formal
