The sequences of the human parainfluenza virus type 3 (PIV3) matrix (M) mRNA [1150 nucleotides exclusive of poly(A)] and predicted M protein (353 amino acids) were determined by sequence analysis of cloned cDNA and viral genomic RNA. The gene-end sequence of the M gene differed from the semi-conserved gene-end sequence of the other PIV3 genes by an apparent insertion of eight nucleotides. The PIV3 M protein shared high sequence homology with Sendai virus and moderate homology with measles virus and canine distemper virus. Statistical analysis of the available sequences showed that the M protein was the most highly conserved parainfluenza viral protein.
通过对克隆的互补脱氧核糖核酸（cDNA）和病毒基因组核糖核酸（RNA）进行序列分析，确定了人3型副流感病毒（PIV3）基质（M）信使核糖核酸（mRNA）的序列[1150个核苷酸，不包括聚腺苷酸（polyA）]以及预测的M蛋白（353个氨基酸）。M基因的基因末端序列与其他PIV3基因的半保守基因末端序列不同，明显插入了八个核苷酸。PIV3 M蛋白与仙台病毒具有高度的序列同源性，与麻疹病毒和犬瘟热病毒具有中等同源性。对现有序列的统计分析表明，M蛋白是副流感病毒中保守性最高的蛋白。
