Thrilled to share our new paper: SLC33A1 is the long-sought ER GSSG exporter, maintaining redox homeostasis in the ER. Huge congratulations to my co-first author @shanshanliu1218 and my PIs @KivancBirsoy and @HiteLabMSKCC for leading this work. nature.com/articles/s41556-0… 🧵 1/9

Excited to share our new work! We identified SLC33A1 as the major ER GSSG exporter that maintains redox balance in the ER lumen.

Our new work by @shanshanliu1218 and @gadmark addresses a fundamental question: how does ER maintain its unique oxidizing environment, while rest of the cell is reducing? Here, we identify SLC33A1 as the major ER GSSG exporter in mammalian cells. nature.com/articles/s41556-0…

In @NatureCellBio: @KivancBirsoy's lab has discovered that the antioxidant glutathione plays a vital role in maintaining smooth operations of a protein-producing hub in the cell called the endoplasmic reticulum by acting as a protein “proofreader.”

California state reservoir levels are now at 130% of normal, holding 7 trillion gallons of water.
Remarkable.

The FTC called Metsera and, apparently, told them that Pfizer was right about the structure of Novo's deal.
Pfizer wins.
