摘要: A novel ganglioside-induced differentiation-associated protein 1 gene (BmGDAP1) was first cloned and sequenced from silkworm, Bombyx mori using rapid amplification of cDNA ends (RACE). The full-length cDNA of BmGDAP1 was 1514. bp, consisting of a 91. bp 5' untranslated region (UTR), a 424. bp 3'-UTR and a 999. bp open reading frame (ORF). The ORF encoded a polypeptide of 332 amino acids, which possessed a thioredoxin (TRX)-like domain, a glutathione S-transferase-C (GST-C) family domain and a transmembrane segment. Furthermore, quantitative real-time PCR analysis revealed that BmGDAP1 transcripts were mainly presented in the tissues of hemocytes and midgut of silkworm, and its expression level was down-regulated in the hemocytes, while up-regulated in the midgut. Therefore, it could be concluded that BmGDAP1 plays an important role in the recognition and immune response of silkworm to BmCPV infection.
