Abstract

Calcium influx in response to extracellular signals can modulate gene transcription. A constitutive, calcium/calmodulin-independent mutant of type II calcium/calmodulin-dependent protein kinase was capable of increasing the transcription rate of specific genes independently of protein kinase C activation. This increase was mediated by transferable cis-active elements capable of binding the transcription factor CAAT/enhancer binding protein. Therefore, the activation of type II calcium/calmodulin-dependent protein kinase in response to stimuli that increase intracellular calcium is proposed to represent a distinct second messenger pathway in calcium-mediated regulation of gene transcription.
