Abstract

The cloning, sequencing and functional expression of Sgβ1, a novel locust (Schistocerca gregaria) non-α nicotinic acetylcholine receptor (nAChR) subunit is described. This subunit shows 80% identity with the Drosophila melanogaster Dβ1 and 92% identity with the Locusta migratoria β1, non-α subunits but only 38% identity to Sgα1 (also referred to as αL1), a previously cloned S. gregaria nAChR α-subunit. When expressed in Xenopus laevis oocytes, Sgβ1 does not respond to nicotine. Responses to nicotine are observed, however, in oocytes co-expressing Sgα1 and Sgβ1, but the pharmacology is indistinguishable from that of currents produced by expressing Sgα1 alone. We conclude that either Sgβ1 does not co-assemble with Sgα1, or that it is unable to contribute to the functional properties of the receptor, in the Xenopus oocyte expression system.
