ORF34 physically interacts with ORF24, ORF31, ORF18, ORF23, and ORF66. Cells (293T) were co-transfected with 2xS-tagged ORF34 and 6xMyc-ORF24 (a), 3xFLAG-ORF31 (b), 3xFLAG-ORF18 (c), 3xFLAG-ORF66 (d), 3xFLAG-ORF30 (e), or 6xMyc-ORF23 (f), upper panel) expression plasmids. Cell lysates were subjected to pull-down assays using S-protein-immobilized beads, which captures S-tagged ORF34. The precipitates were immunoblotted with anti-Myc or FLAG antibody to detect their interactions. (e) The pull-down sample was precipitated from cell extracts co-transfected with 2xS-ORF34 and 3xFLAG-ORF31, was applied in the left lane as the positive control. (f), lower panel) The pull-down sample was precipitated from cell extracts co-transfected with 2xS-ORF23 and 6xMyc-ORF34. (af) Original images of blotting data are shown in Supplementary Figs S3S8. (g) Schematic depiction of the interactions between KSHV ORF34 and KSHV-PIC component candidates.
