Resumo: | Elongation factor 1A is a highly conserved protein that participates in translation. We report the occurrence of two genes homologous to the eukaryotic Elongation Factor 1A in Bradysia hygida and describe the partial cloning and characterization of the B. hygida eukaryotic Elongation Factor 1A-F1 (BheEF1A-F1) gene. The pattern of BheEF1A-F1 expression in the salivary gland at the end of the fourth larval instar was investigated using real-time PCR. The results showed that BheEF1A-F1 expression levels are relatively constant at the time when rapid changes in protein synthesis occur in this tissue. In situ hybridization experiments coupled to Southern blot analyses showed that the BheEF1A-F1 gene is located at position 3d of the A chromosome and a second gene homologous to eEF1A is located at position 6a of the X chromosome. Southern blot analyses showed that both the BheEF1A-F1 gene and the second gene homologous to eEF1A constitute non-amplified genes. The present results contribute to the molecular characterization of a sciarid eEF1A gene.
