Peripheral membrane protein {ECO:0000305|PubMed:26251452}. Note=Associates with the external leaflet of the plasma membrane (By similarity). S-acylated NEU3 likely spans the lipid bilayer with a portion of C-terminus exposed to the cytosol and the catalytic region facing the extracellular space (PubMed:28646141). {ECO:0000250|UniProtKB:Q9JMH7, ECO:0000269|PubMed:28646141}.
