Targeting of protein kinases and phosphatases to the cytoskeleton enhances the regulation of many signalling events. Cytoskeletal signalling complexes facilitate this process by optimizing the relay of messages from membrane receptors to specific sites on the actin cytoskeleton. These signals influence fundamental cell properties such as shape, movement and division. Targeting of the cAMP-dependent kinase (protein kinase A) and other enzymes to this compartment is achieved through interaction with A-kinase-anchoring proteins (AKAPs). The present paper discusses recent progress on dissecting the biological role of WAVE1 (Wiskott–Alrich syndrome protein family verprolin homology protein 1), an AKAP that assembles a cytoskeletal transduction complex in response to signals that emanate from the low-molecular-mass GTPase, Rac.

ABSTRACT Studies have been performed to investigate the regulation of arginine vasopressin (AVP) mRNA expression in fetal hypothalamic cultures. AVP mRNA-positive neurones were identified by in-situ hybridization histochemistry, and changes in mRNA expression were quantitated by nuclease protection assay. Both protein kinase C and protein kinase A activators increased the expression of AVP mRNA, in contrast to dexamethasone, which inhibited the responses to both protein kinase C and protein kinase A activation.
