Targeting the Lysosomal Degradation of Rab22a‐NeoF1 Fusion Protein for Osteosarcoma Lung Metastasis

Abstract excerpt

Rab22a-NeoF fusion protein has recently been reported as a promising target for osteosarcoma lung metastasis. However, how this fusion protein is regulated in cells remains unknown. Here, using multiple screenings, it is reported that Rab22a-NeoF1 fusion protein is degraded by an E3 ligase STUB1 via the autophagy receptor NDP52-mediated lysosome pathway, which is facilitated by PINK1 kinase. Mechanistically,...
