Predicted to enable acyltransferase activity, transferring groups other than amino-acyl groups; extracellular ligand-gated monoatomic ion channel activity; and transmembrane signaling receptor activity. Predicted to be involved in monoatomic ion transmembrane transport. Predicted to be located in membrane. Is an ortholog of C. elegans acr-11. In C. elegans, acr-11 is involved in chemical synaptic transmission.
