(a) NRBF2 is critical for the assembly of Vps34-Vps15 and Atg14L-Beclin 1 complex. Brain lysate from WT and NRBF2 KO mice were subjected to co-IP by Vps34 antibody and Atg14L antibody. The IP products were subjected to in vitro lipid KA and WB analysis using the indicated antibodies. (b,c) Quantification results shows that Vps34-Vps15 and Atg14L-Beclin 1 complex interactions as well as Atg14L-linked Vps34 kinase activity are markedly impaired in NRBF2 KO mice. (Data are shown as mean±s.e.m., P values are indicated on the figures, unpaired Student's t-test, n=4 mice in each group; NS, not significant).
