Webchains in vivo [26,27], although the function of polyneddylation remains to be determined. NEDD8, like ubiquitin, contains the evolutionary conserved canonical hydrophobic patch, … WebBecause Myc:AXR1 cannot be efficiently separated from neddylated cullins in anti-NEDD8 immunoblots, we examined Myc:AXR1 abundance and neddylation using anti-Myc immunoblots. There, we found that increases in the NEDD8 gene dosage also led to increased multi- or polyneddylation of AXR1 (Fig. 7D, AXR1-N8 (2×), lane 6).
