[Cloning and analysis of two Cry1Ac receptor-like aminopeptidase N cDNA fragments from Trichoplusia ni (Hübner) cultured cell]
Acta Entomologica Sinica 47 (3), 412-416
Abstract: Some aminopeptidase N (APNs) serve as Bacillus thuringiensis (Bt) Cry1Ac toxin receptor in the midguts of several lepidopteran insects. Two fragments of two different APN genes in BTI-TN-5B1-4 (a cloned cell line from Trichoplusia ni ovary) were amplified with two pairs of degenerate primers by RT-PCR, and the lengths of them were 188 by and 564 bp, and named AS188 (GenBank Accession: CD809324 ) and AS564 (GenBank Accession: CD809326 ) respectively. Deduced protein sequences were highly similar to that of several receptor APNs in insects, with sequence identities of 45% - 47% for the shorter one and 61% - 63% for the other.
