PG - 69-76 LID - 10.1007/s11262-015-1218-5 [doi] AB - To promote viral entry, replication, release, and spread to neighboring cells, many cytolytic animal viruses encode proteins responsible for modification of host cell membrane permeability and for formation of ion channels in host cell membranes. Scylla serrata reovirus (SsRV) is a major pathogen that can severely damage mud crab (S. serrata) aquaculture. Protein p35, which is encoded by segment 10 of SsRV, contains two transmembrane domains. In this study, we found that SsRV p35 can induce membrane permeability changes when expressed in Escherichia coli. SsRV p35 expressed in bacterial cells existed as monomers under reducing conditions but formed homodimers and homotrimers under non-reducing conditions. These findings demonstrate that p35 may act as a viroporin; further studies are needed to elucidate the detailed structure-function relationships of this protein.
