Abstract:
We have previously shown that non-structural protein p35, encoded by Scylla serrata reovirus (SsRV) S10, may act as a viroporin. To characterize the role of p35 protein in the modulation of cellular function, a yeast two-hybrid system was used to screen a cDNA library derived from S. serrata to find its interacting partner. Protein interactions were confirmed in vitro by GST pull-down. Full cDNAs of p35 interactors were cloned by the rapid amplification of cDNA ends. After two-hybrid library screening, we isolated partial cDNAs encoding hemocyanin, cryptocyanin, and TAX1BP1. Interaction of p35 with each of hemocyanin, cryptocyanin, and TAX1BP1 was confirmed by GST pull-down. The full-length cDNA fragments of hemocyanin, cryptocyanin, and TAX1BP1 were 2287, 2422, and 3437 bp, respectively, and they encoded three putative proteins with molecular masses of ~76.9, ~79.2, and ~107.2 kDa, respectively. This study casts new light on the function and physiological significance of p35 during the SsRV replication cycle.

SNAREs and Membrane Fusion
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...
