Larger Image Figure 8. DCC phosphorylation on tyrosine 1418 is critical for Netrin-1–induced Rac1 activation. (A) COS-7 cells coexpressing DCC, Y1261F-, or Y1418F-DCC mutants together with Myc-Rac1 protein were or were not treated with Netrin-1 for 5 min. The GTP-loaded Rac1 were pulled down from the cell lysates using GST-Cdc42/Rac interactive binding domain-Pak1 fusion protein. The proteins from the pull-down and from the total cell lysate were analyzed by Western blot using anti-DCC antibodies and anti-Myc antibodies to detect both Rac1-GTP and the total Rac1. (B) Quantitative analysis of Rac1 activation by DCC and DCC tyrosine mutants after Netrin-1 treatment (n = 5). Error bars represent SD. Image published in: Meriane M et al.
