A Drosophila phospholipase C (PLC) gene, designated as plc-21, was isolated by screening a genomic DNA library using a cDNA for a previously isolated Drosophila PLC gene, norpA, as probe under reduced stringency hybridization conditions. The gene maps to 21C on the left arm of the second chromosome. Two proteins of 1305 and 1312 amino acids, respectively, were deduced from two classes of cDNA which were isolated. The two putative plc-21 proteins are similar in sequence and overall structure to the beta-class of PLCs found in mammals and differ from each other only by 7 amino acid residues that are present near the C terminus of one of the proteins but not the other. Hybridization of plc-21 cDNA probes to blots of poly(A)+ RNA revealed that the gene encodes a 7.0-kilobase transcript that could be detected in the head but not in the body of adult flies and a 5.6-kilobase transcript that could be detected throughout development and in both heads and bodies of adults. In situ hybridization of cDNA sequences to tissue sections showed that the gene is expressed in the neuronal cell bodies of the optic lobe, central brain, and thoracic ganglia of adults and the brain of larvae. This tissue distribution of plc-21 transcripts is identical to the distribution of transcripts from a Drosophila Go alpha-subunit gene that we reported previously.
