  1. 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株均出現了兩個特徵性的突變：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；缺失性突變恰恰位於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。
  2. Rapl belongs to ras superfamily of small gtp - binding proteins, which is considered to control cell growth, differentiation and survival. rapl was regarded as an antagonist of ras because it can revert the phenotype of oncogene ras transformed cells. recent researches show that rapl has its ras - independent functions in a variety of cellular systems besides its effect as an antagonist of ras

    Rap1除具有逆轉原癌基因ras激活突變體所導致的細胞形態改變而被認為是ras的拮抗物外，最近的研究還發現rap1在一系列的細胞系統中有獨立於ras之外的功能，如控制與細胞粘附有關的事件等，因而成為研究的熱點。
