The serpin gene family in Anopheles gambiae.

ABSTRACT: Serpins (serine protease inhibitors) regulate some innate immune responses of insects by inhibiting endogenous proteases. In this study, we characterized the serpin (SRPN) gene family in the mosquito Anopheles gambiae, the major malaria vector in Sub-Saharan Africa. We identified 18 A. gambiae SRPN genes, all on chromosomes 2 and 3, through searches of genomic DNA and EST databases. In addition to SRPN10, previously documented to exhibit alternative splicing, we found three splicing isoforms of SRPN4. We completed sequencing of cDNAs for the A. gambiae serpins to obtain complete coding sequence information and to verify or improve gene predictions. The predicted SRPN9 and 15 in the initial genome annotation were determined to be a single gene (SRPN9). Sixteen of the serpins contained putat
