TCRP1 directly interacts with PDK1 and activates PDK1/AKT signaling.(a) The effects of TCRP1 on the expression of PI3K/Akt and its downstream molecules. (b) 293T and NIH/3T3 cells were co-transfected with EGFP-TCRP1 and pDsred-PDK1, or EGFP-TCRP1 and pDsred-AKT1, the direct interaction between TCRP1 and PDK1, or TCRP1 and AKT1, were determined by forster resonance energy transfer (FRET) assay. Cells co-transfected with EGFP-PDK1 plasmids, and pDsred-AKT1 was used as positive control. (c) Total protein extracts of NIH/3T3 cells were subjected to IP using TCRP1 antibody or control IgG, followed by western blotting (WB) with PDK1 antibody (upper panel). Reciprocal IP was done using PDK1 antibody or control IgG, followed by WB with the TCRP1 antibody (lower panel).
