The Spectrin cytoskeleton regulates the Hippo signalling pathway

GC Fletcher, A Elbediwy, I Khanal, PS Ribeiro… - The EMBO …, 2015 - embopress.org
The Spectrin cytoskeleton is known to be polarised in epithelial cells, yet its role remains
poorly understood. Here, we show that the Spectrin cytoskeleton controls Hippo signalling. In …
