ATPase-coupled ion transmembrane transporter activity obsolete ATPase coupled ion transmembrane transporter activity involved in regulation of presynaptic membrane potential https://github.com/geneontology/go-ontology/issues/31205 true OBSOLETE. Any ATPase coupled ion transmembrane transporter activity, occurring in the presynaptic membrane, that is involved in regulation of presynaptic membrane potential. GO:0099521 The reason for obsoletion is that this term is pre-composed and should be represented as a GO-CAM model.
