Figure 4. TBK1 in control of ubiquitin-dependent autophagy.

Figure 4

TBK1 mediates feedback and feedforward regulation of the two autophagic adaptor proteins p62 and OPTN. Phosphorylation on their UBDs promotes binding to ubiquitylated cargo, whereas phosphorylation of the LIR motifs promotes the recruitment of autophagosomal membranes. Thus, TBK1 amplifies cargo recognition and commits it to degradation.
