Sphingolipids are structural components of membranes, and sphingolipid metabolites serve as signaling molecules. The first and rate-limiting step in sphingolipid synthesis is catalyzed by serine palmitoyltransferase (SPT). The recently discovered SPT-associated proteins, Orm1 and Orm2, are critical regulators of sphingolipids. Orm protein phosphorylation(More)
We have constructed 26-amino acid transmembrane proteins that specifically transform cells but consist of only two different amino acids. Most proteins are long polymers of amino acids with 20 or more chemically distinct side-chains. The artificial transmembrane proteins reported here are the simplest known proteins with specific biological activity,(More)
Though once a discovery greatly celebrated by the nation, the vaccine has come under fire in recent decades from skeptics, critics, and a movement set into motion by fraudulent scientists and fueled by frustrated parents looking for answers to the autism conundrum. There is enough denialist resistance to vaccination to bring upon renewed fear of young(More)
