Figure Lengend Snippet: ERBB3 variants lack the capacity to activate PI3K/AKT and ERK signaling pathways. a Immunoblot analysis was performed using indicated antibodies to determine the effects of WT or mutant ERBB3 on PI3K/AKT and ERK pathway activation. To induce protein phosphorylation, HEK293T cells were treated with 10 ng/ml NRG-1β for 30 min after transfection with empty vector (EV), WT, M1, M2, or M3 (V104 L) plasmids. b–e Quantitative analysis of p-ERK, p-AKT, p-ERBB2, and p–ERBB3 expression. * P < 0.05, ** P < 0.01, *** P < 0.001 vs. WT
