MAP2K7 associates with and degrades the SVCV P protein. (A) EPC cells transfected with the indicated plasmids (5 ?g each). After 24 h, cell lysates were immunoprecipitated (IP) with anti-Flag affinity gels. (B) EPC cells seeded in 10 cm2 dishes were transfected with MAP2K7-HA (5 ?g). After 24 h, the earlier cotransfected cells were infected with SVCV (MOI, 1); 24 h later, cell lysates were IP with anti-HA affinity gels. (C) EPC cells were transfected with 1 ?g P-Flag and 1 ?g MAP2K7-HA for 24 h. (D) EPC cells were transfected with P-Flag (1 ?g) and MAP2K7-HA (0.25, 0.5, or 1 ?g) for 24 h. (E) EPC cells were transfected with MAP2K7-HA. After 24 h, the cells were infected with SVCV (MOI, 1). (F) EPC cells were cotransfected with P-EGPF and vector or MAP2K7-HA for 24 h; then the cells were fixed and subjected to confocal microscopy analysis. Green signals represent the SVCV P protein, and blue staining indicates the nucleus region (original magnification, ×20). Scale bar, 50 ?m. (G and H) EPC cells were transfected with 5 ?g P-Flag and 5 ?g P-HA (2 ?g MAP2K7-Myc). After 24 h, cell lysates were immunoprecipitated (IP) with anti-Flag affinity gels. Then, the immunoprecipitates and cell lysates were analyzed by IB with Abs, respectively. Cell lysates were IP with anti-Flag affinity gels.
