PKR interacts with 4.1R depending on its kinase activity. (A) COS7 cells were transfected with the indicated plasmids, followed by IP and WB. The top panel shows the co-precipitation of PKR with 4.1R by IP with anti-Flag antibody and WB with anti-Myc antibody. The second panel shows the expression of 4.1R by IP with anti-Flag antibody and WB with anti-Flag antibody. The lower two panels show the expression level of each protein without IP. (B) COS7 cells were transfected with the indicated plasmids, followed by IP and WB. The top panel shows the co-precipitation of 4.1R with PKR by IP with anti-Flag antibody and WB with anti-Myc antibody. The second panel shows the expression of PKR by IP with anti-Flag antibody and WB with anti-Flag antibody. The lower two panels show the expression level of each protein without IP. (C) COS7 cells were transfected with the indicated plasmids, followed by IP and WB. The top panel shows the co-precipitation of wild type PKR or PKRK296R with 4.1R by IP with anti-Flag antibody and WB with anti-Myc antibody. The second panel shows the expression of 4.1R by IP with anti-Flag antibody and WB with anti-Flag antibody. The lower two panels show the expression level of each protein without IP.
