Export extravaganza
Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have conducted the first comprehensive census of human cells' export workers. In a study published online today in Nature Cell Biology, they found an unexpected variety of genes involved in transporting molecules to the cell membrane and beyond.
Using a combination of genetics and sophisticated microscopy, Rainer Pepperkok and colleagues systematically silenced each of our 22 000 genes, and observed to what extent this affected the cell's ability to transport a protein. They found that ...
