title: Signal transduction in development: holding the key.
abstract: The unrelated GSK-3 and CK1 families stand out among the protein kinases because of their phosphorylated substrate recognition sites. Two papers in the March 22nd issue of Cell highlight the importance of this priming phosphorylation for signal transduction during development.
