katch wreck`..phosphorylation of Optineurin by TBK1 induces the formation of filaments that phase separate upon binding to linear polyubiquitin.. the condensation of filamentous Optineurin with ubiquitylated cargo promotes the nucleation of cargo and its subsequent alignment with LC3-positive nascent autophagosomes, suggesting that co-condensation processes ensure directionality in selective autophagy`
