摘　　要：昆虫杆状病毒是目前已知唯一编码泛素 (ubiquitin)的病毒。迄今 ,已克隆了 8种该类病毒的泛素基因。与真核生物Uba5 2 (80 )相似 ,这些基因在一个泛素分子的C 末端都有不同长度的融合 ,其中斜纹夜蛾核多角体病毒 (Spodopteralituramulticapsidnucleopolyhedrovirus ,SpltMNPV)的ubiquitin gp37基因是一个典型的融合基因。近年来 ,对苜蓿银纹夜蛾核多角体病毒 (Autographacaliforniamulticapsidnucleopolyhedrovirus ,AcMNPV)Insect baculovirus are the only viruses currently known to encode ubiquitin homologies. At present, seven ubiquitin genes of different insect baculoviruses were cloned. Similarly to Uba52(80) genes of eukaryotes, different length amino acids are fused at the C-terminus of baculovirus ubiquitins. Among them, Spodoptera litura multicapsid nucleopolyhedrovirus (SpltMNPV) ubi-gp37 is a typical ubiquitin fusion gene. Recently, great progress was made in studying on the position and function of Autograph californica multicapsid nucleopolyhedrovirus (AcMNPV) ubiquitin.
