PHOSPHATASES

Pack a STRIPAK with hubs inside a hub

The highly conserved striatin-interacting phosphatase and kinase (STRIPAK) multimeric complex regulates the Hippo signaling pathway through phosphatase activity. A recent structure of the core STRIPAK hub reveals how striatins tetramerize to serve as a scaffolding platform for the assembly of an intricate architecture, which is distinct from that of all other protein phosphatase 2A (PP2A) complexes.
