: ALS and ARD proteins are thought to represent a ligand binding and a structural subunit, respectively, of Drosophila nicotinic acetylcholine receptors (nAChRs). Here, antibodies raised against fusion constructs encompassing specific regions of the ALS and ARD proteins were used to investigate a potential association of these two polypeptides. Both ALS and ARD antisera removed 20‐30% of the high‐affinity binding sites for the nicotinic antagonist 125I‐α‐bungarotoxin (125I‐α‐Btx) from detergent extracts of fly head membranes. Combinations of both types of antisera also precipitated the same fraction of α‐Btx binding sites, a result suggesting that both polypeptides are components of the previously defined class I 125I‐α‐Btx binding sites in the Drosophila CNS. 125I‐α‐Btx binding to a MS2 polymerase‐ALS fusion protein containing the predicted antagonist binding region showed that the ALS protein indeed constitutes the ligand binding subunit of a nicotinic receptor complex. These data are consistent with neuronal nAChRs in Drosophila containing at least two types of subunits, ligand binding and structural ones.
