The comparative analysis of sequences indicated that the sequences of meq in different pathotypes are relatively conserved and the homology of the amino acid sequences is very high . the significant differences include two mutations in both mdv - 1 vaccine strains cvi988 / rispens and 814 strain : the deletion of a proline ( no . l93aa ) , and this mutation is just exactly located in a 15 - amino - acid ( eelcaqlcstppppi ) repeat sequence within the c - terminal transactivation domain of meq protein ; and a point mutation with a shift from alanine ( a ) of all virulent strains to serine ( s ) was occurred on the no . 71 aa 結果發現, mdv不同致病型的meq基因序列相對比較保守,它們相互間核苷酸和氨基酸序列的同源性均很高;但是,與所有七個致瘤性的mdv毒株相比,二個型弱毒疫苗cv1988 rispens株和814株均出現了兩個特征性的突變:即第194位的p缺失性突變和第71位氨基酸由a變成了s的位點突變;缺失性突變恰恰位于meq基因中轉錄激活域內的一個多脯氨酸的重復序列( pppp )之中。

Lfy and lfy - like proteins from angiosperm contain a proline - rich region near the amino terminal and an acidic central region which is typical for transcriptional activators and may be important for the function of lfylike protein . the two domain exists in the variable regions of all lfy - like proteins 與擬南芥leaf ’ y基因相比較,銀杏ginlfy和g毗基因沒有做為轉錄激活區域的位于氨基酸序列中間的酸性區和位于n端的富含脯氨酸區,但這兩個區域均位于leafy基因的非保守區。

Pp38 was found to have immunosuppressive effect on chicken in vivo and the copy number of 132 - bpr was found to be associated with the attenuation of the virus in vitro , meq was believed to be a potential oncogene , based on its leucine zipper structure and proline - rich domain characteristic of jun / fos family of transcription factors , and may plays an important role in the pathogenicity or oncogenicity of mdv 其中, meq與132 - bpr兩個基因是mdv - 1所特有,已證實132 - bpr的拷貝數與毒株的體外致弱程度有關, pp38則被證實可抑制機體的免疫應答。 meq基因由于具有與致瘤基因jun fos家族類似的分子結構,因此,我們有理由認為meq基因在mdv致病、致瘤中可能發揮重要的作用。

Sequence analysis revealed that most of the sequences showed no similarities to the known genes except that only two sequences gave rise to some similarities . in them , one owned a conseved domain of v - atpase - sub - a , another coded a proline - rich protein , which has multiple phosphate sites 通過比較得知,該病毒序列與genbank中已知基因序列的同源性較低,僅兩個片段與已知的基因序列有部分相似,其中一個片段含有v _ atpase _ sub _ a的結構域,另外一個片段序列編碼多磷酸位點的富含脯氨酸的蛋白。
