Calmodulin-dependent protein kinase IV (CaMKIV) is a key mediator of Ca2+-i
nduced gene expression. This serine/threonine kinase is itself activated by
a calmodulin kinase kinase. In the present contribution the gene structure
, regulation of activity, the role in Ca2+-dependent gene expression, and t
he hormonal induction and controlled expression of CaMKIV during tissue dev
elopment are reviewed. (C) 1998 Elsevier Science B.V. All rights reserved.
