[maurizio molinari @MolinariLab]

How does the ER decide whether a misfolded protein is refolded, degraded by ERAD or cleared by ERLAD? Using mutant Neuroserpin, we show that persistent N-glycan glucosylation helps select aggregation-prone proteins for lysosomal clearance.

EBV capsids, 100 nm in diameter. To reach the cytoplasm they cross the inner and outer nuclear membranes held 25–50 nm apart by LINC complex. How?
Epstein Barr virus exploits ER stress and TMX4 dependent nuclear envelope remodeling to enable capsid egress https://t.co/jt7431K9PT

85 anni fa abbiamo scritto una pagina indimenticabile della nostra storia. Con il pareggio casalingo contro i rivali nella corsa al titolo, il BSC Young Boys, abbiamo conquistato il secondo titolo di Campione svizzero.

85 anni di memoria, passione e appartenenza 🤍🖤 ✨

News on ERLAD: Calnexin:FAM134B:VAPA:ORP1L:RAB7 contact site between ER and endolysosomes to remove misfolded proteins.
CNX:FAM134B-driven ERLAD of ATZ polymers proceeds via enhanced formation of VAPA:ORP1L:RAB7 contact sites between ER and endolysosomes https://t.co/auNUg5jtgZ

Today’s NCB. The cytoplasmic intrinsically disordered regions (IDRs) of ER-phagy and mitophagy receptors are interchangeable, required and sufficient for the ER and mitochondria fragmentation required for lysosomal clearance of the organelle’s portions.

Selective autophagy of organelles: the “disorder” is key. Intrinsically disordered regions of organellophagy receptors are interchangeable, required, and sufficient for organelle fragmentation and lysosomal delivery … and all about ORGATACs 😉

ATZ polymers elicit intervention of the CNX:FAM134B-LC3II segregation complex and formation of VAPA-ORP1L-RAB7 membrane contact sites that facilitate Syntaxin18/VAMP8-driven fusion of ER and endolysosomal membrane: ER-to-Lysosome-Associated Degradation.
