Regulation of the ER-Resident Mannosidase EDEM2 in HEK293 Cells

Abstract EDEM2 plays an important role as the first enzyme that acts during mannose trimming of N-glycosylated proteins in the ERAD machinery. Although EDEM2 expression has been reported to be transcriptionally regulated by the IRE1-sXBP1 pathway, very little is known about how endogenous EDEM2 protein expression is regulated. In this…

Validation of transfection and expression of protein constructs within HEK293 cells.

To enable an analysis of Nrxn and Nlgn pairing, we coexpressed different Nrxn and Nlgn constructs with specific nanobarcode proteins. This enables us to provide the different Nrxn- and Nlgn-containing cells with a recognizable identity, without having to modify the additional proteins themselves by nanobarcode tagging. However, this implies that…
