TRIM50

E3 ubiquitin-protein ligase that ubiquitinates Beclin-1/BECN1 in a 'Lys-63'-dependent manner enhancing its binding to ULK1. In turn, promotes starvation-induced autophagy activation. Also interacts with p62/SQSTM1 protein and thereby induces the formation and the autophagy clearance of aggresome-associated polyubiquitinated proteins through HDAC6 interaction. Also promotes NLRP3 inflammasome activation by directly inducing NLRP3 oligomerization independent of its E3 ligase function (By similarity)..
