摘要: Apolipophorin III (ApoLp-III) is a well-known hemolymph protein having functional role in lipid transport and immune responses of insects. Here we report the molecular characterization Anopheles stephensi Apolipophorin-III (AsApoLp-III) gene. This gene consists 679 nucleotides arranged into two exons 45 bp 540 that give an ORF encoding 194 amino acid residues. Excluding putative signal peptide first 19 residues, 175-residues mature AsApoLp-III has calculated mass 22 kDa. Phylogenetic analysis revealed divergence mosquitoes (Order Diptera) ApoLp-III from their counterparts moths (Order: Lepidoptera). Also, it close relatedness to An. gambiae. mRNA expression strongly induced Plasmodium berghei infected mosquito midguts suggesting its crucial parasite development. silencing decreased P. oocysts numbers by 7.7 fold against controls. These effects might be due interruption mediated delivery developing oocysts. In addition, nitric oxide synthase (NOS), antiplasmodial gene, also highly silenced this acts like agonist protects immunity.
