How do cells achieve specific and efficient control over a wide spectrum of activities in the context of a limited protein repertoire? A possible answer comes from the recent demonstration that utilization of distinct enzymes by the same A-kinase anchoring protein (AKAP) depends on the AKAP-bound substrate, thus vastly increasing the diversity of AKAP-mediated protein regulation.
