To achieve high biological specificity, protein kinases and phosphatases often recognize their targets through interactions that occur outside of the active site. Although the role of modular protein-protein interaction domains in kinase and phosphatase signaling has been well characterized, it is becoming clear that many kinases and phosphatases utilize docking interactions - recognition of a short peptide motif in target partners by a groove on the catalytic domain that is separate from the active site. Docking is particularly prevalent in serine/threonine kinases and phosphatases, and is a versatile organizational tool for building complex signaling networks; it confers a high degree of specificity and, in some cases, allosteric regulation.
