Molecular characterization and phylogenetic analysis of the eukaryotic translation initiation factor 4A gene in Antheraea pernyi (Lepdoptera: Saturniidae).

ABSTRACT: Eukaryotic initiation factor 4A (eIF-4A) is an essential component for protein translation in eukaryotes. The eIF-4A gene (ApeIF-4A) was isolated and characterized from Antheraea pernyi (Guérin-Méneville) (Lepidoptera: Saturniidae). The obtained cDNA sequence was 1,435-bp long with an open reading frame of 1,266 bp encoding 421 amino acids. The predicted amino acid sequence shared several conserved features as found in known eIF-4As and revealed 74 and 78% identities with eIF-4As of Homo sapiens L. and Drosophila melanogaster (Meigen), respectively. Reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that ApeIF-4A was transcribed at four developmental stages and in all tissues tested, suggesting that it plays an important role in development of A. pernyi.
