Calcium (Ca2+) signals regulate a diverse set of cellular responses, from proliferation to muscular contraction and neuro-endocrine secretion. The ubiquitous Ca2+ sensor, calmodulin (CaM), translates changes in local intracellular Ca2+ concentrations into changes in enzyme activities. Among its targets, the Ca2+/CaM-dependent protein kinases I and IV(More)
Bacterial pathogens have evolved specific effector proteins that, by interfacing with host kinase signalling pathways, provide a mechanism to evade immune responses during infection. Although these effectors contribute to pathogen virulence, we realized that they might also serve as valuable synthetic biology reagents for engineering cellular behaviour.(More)
The multifunctional calcium/calmodulin-dependent protein kinases I and IV (CaMKI and CaMKIV) are closely related by primary sequence and predicted to have similar substrate specificities based on peptide studies. We identified a fragment of p300-(1-117) that is a substrate of both kinases, and through both mutagenesis and Edman phosphate ((32)P) release(More)
