EV-surface aptamer targets — membrane-surface vs cargo, ranked (view)

PREDICTED EV-surface accessibility (not a measurement). EV biogenesis normally preserves membrane topology, so we predict which targets present an extracellular epitope on an INTACT vesicle. surface_class A_surface = integral/ecto cell-surface (CD/GPCR/ion-channel/integral membrane). A2_pm_peripheral = plasma-membrane but cytoplasmic-leaflet (SRC/LYN/RHOA/FLNA) — predicted NOT reachable. A_assoc = secreted / surface-corona. CAVEATS: HPA gives cellular (not EV) localization; lipid asymmetry can partially flip (phosphatidylserine externalizes via scramblase TMEM16F on activated/platelet/apoptotic EVs); cytoplasmic proteins can attach as a protein corona; EV populations are heterogeneous. CONFIRM by protease-protection (proteinase K +/- detergent), intact-EV surface labelling / bead-capture flow, or immuno-EM. Classification from HPA subcellular localization + protein class (Thul 2017; Uhlén 2015). targetability_score is a transparent composite, not experimental.

surface_class
PREDICTED topology: A_surface (ecto, predicted accessible) / A2_pm_peripheral (cytoplasmic leaflet, predicted not accessible) / A_assoc (secreted/corona). Confirm experimentally.
surface_evidence
Which HPA field drove the call (no fabrication).
ev_map_hallmark
1 = EV-Map conserved EV-hallmark protein (Rai & Greening 2025) — strongest evidence it is on circulating EVs.
targetability_score
Composite: 1.0[integral surface] + 0.8[EV-Map hallmark] + 0.3[in EV proteome] + 0.4[has PDB] + 0.3 min(disease,1) + 0.2[approved drug]. Heuristic, NOT experimental.
pdb_count
Experimental PDB structures available to design against.
disease_score
Open Targets top disease association score.
