The Hippo signaling pathway plays key roles in many processes, from cell
proliferation and cell death to regulation of stem cells and cancer cells.
Kwon et al. (p. 737, published 10 October) attempted to systematically
identify all components of the pathway. A protein-protein interaction screen
identified more than 200 interactions among approximately 150 proteins. A
protein identified in the screen, Leash, restrained the activity of the
transcriptional coactivator Yorkie, which regulates gene expression in
response to Hippo signaling.
