EN6 is a small-molecule in vivo autophagy activator that covalently targets cysteine 277 in the ATP6V1A subunit of the lysosomal v-ATPase. EN6-mediated modification of ATP6V1A uncouples v-ATPase from Rag, leading to inhibition of mTORC1 signalling, increased lysosomal acidification, and activation of autophagy. EN6 also scavenges TDP-43 aggregates (causative agents of frontotemporal dementia) in a lysosome-dependent manner.

Description

In Vitro

EN6 (50 μM; 1, 4, 8 h) increases the levels of LC3BII, and triggers formation of LC3 puncta in a time- and dose-dependent manner, in HEK293A cells^[1].
? EN6 leads to significant increases in the number autophagosomes and autolysosomes in HEK293A cells^[1].
? EN6 (25 μM; 1 h) blocks mTORC1 lysosomal localization and activation in HEK293A cells^[1].
? EN6 (50 μM; 4 h) activates the v-ATPase and lysosome acidification in HEK293A cells^[1].
? EN6 (25 μM; 7 h) promotes autophagic clearance of protein aggregates in IPTG-inducible GFP-TDP43 U2OS osteosarcoma cell line model^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
