A gene encoding a receptor for activated protein kinase C1 homolog has been isolated from the shrimp, Penaeus monodon (Pm-RACK1). The full length Pm-RACK1 cDNA has 957 bp, and an open reading frame encoding a protein of 318 amino acid residues. The protein contains seven WD40 repeats and shares approximately 78% identity with vertebrate RACK1. In adult shrimp, Pm-RACK1 transcripts were detected in all tissues. During WSSV infection, Pm-RACK1 was upregulated in hepatopancreas, stomach and hemocytes. We identified Pm-RACK1 as a specific cellular target protein for VP9, a nonstructural protein of WSSV. The interaction of these two proteins may be involved in mediating intracellular VP9 functions.
已从斑节对虾(Penaeus monodon)中分离出一种编码活化蛋白激酶C1同源物受体的基因(Pm-RACK1)。Pm-RACK1 cDNA全长957 bp,有一个编码318个氨基酸残基蛋白质的开放阅读框。该蛋白质包含七个WD40重复序列,与脊椎动物RACK1的同源性约为78%。在成年对虾中,所有组织均检测到Pm-RACK1转录本。在白斑综合征病毒(WSSV)感染期间,肝胰腺、胃和血细胞中的Pm-RACK1上调。我们确定Pm-RACK1是WSSV非结构蛋白VP9的特异性细胞靶蛋白。这两种蛋白质的相互作用可能参与介导细胞内VP9的功能。
