Ask A Scientist - What are mitochondria?

Whitehead Institute Member Jonathan Weissman and colleagues used large-scale systematic genetic screens to identify the molecules and pathways that populate the mitochondrial surface with important and diverse signaling proteins. They deciphered the logic by which the cell ensures the proper delivery of these proteins. These findings may have important implications for understanding the impact on health and disease when these processes go awry.

Whitehead-Broad team harnesses new pooled, image-based screening method to probe the functions of over 5,000 essential genes in human cells.

Much of biology is defined by activity: the rapid growth of an embryo, or the adventurous life cycle of a parasite, or the frenzied evolution of cancer cells. But for two Whitehead Institute researchers, there is much to learn by studying periods of rest.
