AMPKαl interacts with TRAF6 and BECN1 proteins. (A) Mock control vector, MYC-TRAF6, or FLAG-AMPKαl was transfected into HEK293T cells as indicated. Immunoprecipitation (IP) assay was performed with anti-MYC antibody. Immuno-blot membrane was probed with antibodies specific for MYC or FLAG. (B) HEK293T cells were transfected with mock vector, MYC-AMPKαl, FLAG-TRAF6 wild type (WT), or FLAG- truncated mutants of TRAF6 as indicated. IP assay was performed with anti-MYC antibody. IP samples were separated by SDS-PAGE and probed with anti-MYC or anti-FLAG antibody. (C) HEK293T cells were transfected with mock vector, MYC-TRAF6, FLAG-AMPKαl WT, or FLAG-truncated mutants of AMPKαl as indicated. IP assay was performed with anti-MYC antibody. IP samples were separated by SDS-PAGE and probed with anti-MYC or anti-FLAG antibody. (D) A schematic view of molecular interactions between TRAF6 and AMPKαl. (E) Mock control vector, MYC-BECN1, or FLAG-AMPKαl was transfected into HEK293T cells as indicated. IP assay was performed with anti-MYC antibody. Immuno-blot membrane was probed with antibodies specific for MYC or FLAG. (F) HEK293T cells were transfected with mock vector, MYC-BECN1, FLAG-AMPKαl WT, or FLAG-truncated mutants of AMPKαl as indicated. IP assay was performed with anti-FLAG antibody. IP samples were separated by SDS-PAGE and probed with anti-MYC or anti-FLAG antibody. (G) HEK293T cells were transfected with mock vector, FLAG-AMPKαl, MYC-BECN1 WT, or MYC-truncated mutants of BECN1 as indicated. IP assay was performed with anti-MYC antibody. IP samples were separated by SDS-PAGE and probed with anti-MYC or anti-FLAG antibody. (H) A schematic view of molecular interactions between BECN1 and AMPKαl.
