To date, 11 members (α2-α9 and β2-β4) of the neuronal nicotinic acetylcholine receptor gene family have been identified. These genes encode subunits that form distinct receptors with different pharmacological and physiological profiles in temporally and spatially restricted patterns within the nervous system. Distinct molecular mechanisms probably orchestrate the expression of various receptor subtypes, yet little is known of specific transcriptional regulatory elements and their associated factors that are responsible for this segregated pattern of expression. Here we report the identification of an element, in the 5′-flanking region of the rat β4 subunit gene, containing a CA box that is necessary for β4 promoter activity in a transiently transfected cholinergic cell line, SN17. This element was shown to interact with a protein(s) in SN17 nuclear extracts that is antigenically related to the transcriptional activator Sp1. Furthermore, co-transfection experiments confirmed that Sp1 can transactivate a β4 promoter-reporter gene construct, indicating that Sp1 is necessary, at least in part, for transcriptional activation of the β4 subunit gene.
