a Presence of AKT in immunoprecipitate of TMCC3 from AS-B634 using anti-TMCC3 antibody. b, c MDA-MB231 cells transfected with flag-tagged full-length (FL)-TMCC3 and HA-tagged AKT were subject to co-immunoprecipitation assay using anti-flag antibody (b) or anti-HA antibody (c), followed by immunoblotting. d Diagram of full-length TMCC3 and truncated forms of TMCC3 containing 1-153 a.a., 1-282 a.a., 154-282 a.a., 283-416 a.a. e Co-immunoprecipitation analysis of flag-tagged TMCC3 with HA-tagged AKT proteins. 293T cells were transfected with a plasmid encoding HA-tagged AKT and another plasmid encoding flag tag alone or various flag-tagged TMCC3 forms: full-length (FL), 1-153 a.a., 1-282 a.a., 154-282 a.a., or 283-416 a.a. f Flowchart of luminex immunosandwich assay. Detailed procedures were described in “Materials and methods”. g Mean fluorescence intensities (MFI) showed AKT bound to beads coupled with 1-158 a.a. domain of TMCC3 proteins (n = 4). h Levels of pAKTS473 and total AKT were examined in flag-tagged full-length (Flag-FL), 1-153 a.a.- or 154-477 a.a.-truncated TMCC3 transfected MCF7 and MDA-MB231 (MB231) by western blot analysis. Mammosphere forming capacities (i) and migration abilities (j) were assessed in cells transfected with flag-tagged full-length (Flag-FL), 1-153 a.a.- or 154-477 a.a.-truncated TMCC3. i Sphere numbers were calculated after culture for 7 days. #p < 0.001, ##p < 0.0001 (n = 8, t-test). j The numbers of migrated cells in each group were determined in trans-well migration assay. *p < 0.05, **p < 0.01 (n = 3, t-test).
