Proteolytic Remodeling of Cargo Receptor Networks by RHBDL4 Tunes Secretory Pathway Flux

Susanne S Steigleder, Clara Neumann, Marina Tauber…·Marius K. Lemberg

This study identifies RHBDL4 as a protease that remodels cargo receptor networks, modulating secretory pathway flux by cleaving ERGIC cargo receptors and affecting lysosomal protein secretion.

A Golgi-bypass secretion mechanism for proTGFα involving TMED9 and GRASP65

Susanne S Steigleder, I Döring, Marina Tauber…·Marius K. Lemberg

The paper identifies a Golgi-bypass secretion mechanism for proTGFα involving TMED9 and GRASP65, independent of RHBDL4 and utilizing autophagy and ESCRT components.
