Abstract

Genomic DNA corresponding to the soluble guanylyl cyclase β-subunit (GCSβ) gene was cloned and sequenced from Anopheles gambiae. The sequence was 8103 bp long and presumably included the entire coding region. The deduced amino acid sequence was 71% and 62% similar to previously known Drosophila and vertebrate GCSβ, while the C-terminus of A. gambiae GCSβ was shorter. Because of the conserved characteristics in each functional domain, the high G+C% in the third codon positions compared to the introns, the lack of internal stop codons, and the fact that we identified the gene from a cDNA, we conclude that this A. gambiae gene is functional. This is the first detailed description of a guanylyl cyclase gene structure (e.g. intron-exon boundaries). Interestingly, within the fifth intron we found high similarity to the flanking regions of the Pegasus-27 transposable element and other noncoding regions of the A. gambiae genome.
