The Gp78 ubiquitin E3 ligase drives mitophagy by regulating omegasome formation

Milene Ortiz‐Silva, Bharat Joshi, Jerry Zheng, Ren Takimoto, Sanchit Chopra, Nozomu Yachie, Ghassan Hamarneh, Ivan R. Nabi

This study shows Gp78 ubiquitin ligase regulates omegasome formation and mitochondrial protein degradation during mitophagy, independent of PINK1 and Parkin.

CLIC-dependent internalization of caveolin-1 to lysosomal vacuoles in response to osmotic regulation

Timothy H. Wong, Matheus F. Lima, Aditya Nagrath, Y. Lydia Li, Bharat Joshi, FuiBoon Kai, Ivan R. Nabi

The paper shows that caveolin-1 is internalized via CLIC-dependent endocytosis to lysosomal vacuoles in response to osmotic changes, defining a new recycling pathway for membrane buffering.

Gp78 E3 ubiquitin ligase mediates both basal and damage-induced mitophagy

Bharat Joshi, Yayha Mohammadzadeh, Guang Gao, Ivan R. Nabi

This study identifies Gp78 as an E3 ubiquitin ligase that mediates both basal and damage-induced mitophagy through distinct mechanisms involving mitochondrial homeostasis and PINK1.
