    ANTENNAL IONOTROPIC RECEPTORS -
    Ionotropic Receptors (IR) expressed in antennal sensory neurons in Drosophila are largely thought to act as odor-responsive ion channels. IRs are a subfamily of ionotropic glutamate receptors that do not bind glutamate. Some only form functional receptors in the presence of coreceptor IRs. The profile of expression of IRs, together with broadly expressed co-receptors underlies the precise odor-responsiveness of subpopulations of antennal neurons. (Adapted from FBrf0222310).

      Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.

      cDNA clones, fully sequenced
      BDGP DGC clones
      Other clones
        Drosophila Genomics Resource Center cDNA clones

        For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
