title: Cloning and characterization of 40S ribosomal protein S4 gene from Culex pipiens pallens.
abstract: The 40S ribosomal protein S4 gene (RPS4) has been cloned from Culex pipiens pallens. An open reading frame (ORF) of 789 bp was found to encode a putative 262 amino acid protein. The deduced amino acid sequence shares 96% and 91% identity with RPS4 genes from Aedes and Anopheles respectively. Transcript expression of RPS4 was determined by real-time PCR in all life stages of deltamethrin-susceptible and -resistant strains. The results demonstrated that this gene is expressed at all developmental stages. Meanwhile, in pupae and adults, RPS4 is overexpressed in deltamethrin-resistant strain than in -susceptible strain. Our data for the first time suggests that increased expression of the RPS4 gene may play some role in the development of deltamethrin resistance in C. pipiens pallens.
