The matrix (M) gene of influenza virus has been implicated as a determinant of virulence for mouse brain and lung. Comparison of the M gene sequences of the mouse brain adapted variants A/NWS/33 and A/WSN/33 to their parent, A/WS/33, identified two specific amino acid substitutions in the M1 protein which correlated with virulence for mouse: Ala41-->Val and Thr139-->Ala.
流感病毒的基质(M)基因已被认为是小鼠脑和肺毒力的决定因素。将适应小鼠脑的变异株A/NWS/33和A/WSN/33的M基因序列与其亲本A/WS/33进行比较,在M1蛋白中鉴定出两个与小鼠毒力相关的特定氨基酸取代:Ala41→Val和Thr139→Ala。
