为探究赤眼鳟遗传学和生理学实验室蛋白2 (laboratory of genetics and physiology 2, LGP2)的功能特征及抗草鱼呼肠孤病毒(grass carp reovirus, GCRV)育种参考潜力,实验克隆获得了2 940 bp的赤眼鳟lgp2(Sclgp2)全长cDNA和721 bp的5’端上游序列。Sclgp2 cDNA编码680个氨基酸,包含DEXDc (DExD/H-box helicase domain)、HELICc (helicase superfamily C-terminal domain)和CTD (C-terminal regulatory domain)结构域;其5’端上游序列含有MafB (muscle aponeurosis fibromatosis B)和IRF3 (interferon regulatory factor 3)等转录因子结合位点。不同物种LGP2的功能结构域、...
