Molecular cloning of two pheromone binding proteins in the cabbage armyworm Mamestra brassicae.

ABSTRACT

Two cDNA clones encoding pheromone binding proteins (PBPs) were isolated from antennal cDNA of Mamestra brassicae by reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends-PCR (RACE-PCR) performed with specific primers deduced from the N-terminal sequences of two PBPs previously reported. The deduced protein sequences of the two PBPs showed a strong relationship between primary structures and functional properties of the corresponding mature proteins.
