A-kinase-anchoring proteins [PDF]
Highly organized molecular complexes determine the precise location and timing of the signal transduction events that occur downstream of cell surface receptor activation ([Pawson and Nash, 2003][1]). One set of scaffolding molecules that organize such complexes is a family of proteins known as A-

Protein Kinase A Anchoring [PDF]
Specificity is perhaps the most enigmatic property of hormonemediated signaling pathways, especially when one considers that more than 30 hormones employ the ubiquitous second messengers, Ca, phospholipid, or cAMP, to relay messages from the cell membrane to intracellular effectors.

Protein Kinase A in Cancer [PDF]
In the past, many chromosomal and genetic alterations have been examined as possible causes of cancer. However, some tumors do not display a clear molecular and/or genetic signature. Therefore, other cellular processes may be involved in carcinogenesis.

A-kinase-interacting protein localizes protein kinase A in the nucleus [PDF]
The genetic variability and covalent modifications associated with the amino terminus of the protein kinase A (PKA) catalytic (C) subunit suggest that it may contribute to protein–protein interactions and/or localization. By using a yeast two-hybrid screen, we identified a PKA-interacting protein (AKIP1) that binds to the amino terminus (residues 1–39)

Physiological Phosphorylation of Protein Kinase A at Thr-197 Is by a Protein Kinase A Kinase [PDF]
Phosphorylation of the catalytic subunit of cyclic AMP-dependent protein kinase, or protein kinase A, on Thr-197 is required for optimal enzyme activity, and enzyme isolated from either animal sources or bacterial expression strains is found phosphorylated at this site.

Protein Kinase Inhibitor Peptide as a Tool to Specifically Inhibit Protein Kinase A [PDF]
The protein kinase enzyme family plays a pivotal role in almost every aspect of cellular function, including cellular metabolism, division, proliferation, transcription, movement, and survival. Protein kinase A (PKA), whose activation is triggered by cyclic adenosine monophosphate (cAMP), is widely distributed in various systems and tissues throughout ...

WNKs: protein kinases with a unique kinase domain [PDF]
WNKs (with-no-lysine [K]) are a family of serine-threonine protein kinases with an atypical placement of the catalytic lysine relative to all other protein kinases. The roles of WNK kinases in regulating ion transport were first revealed by the findings that mutations of two members cause a genetic hypertension and hyperkalemia syndrome.

Edmond Fischer's kinase legacy: History of the protein kinase inhibitor and protein kinase A
AbstractAlthough Fischer's extraordinary career came to focus mostly on the protein phosphatases, after his co‐discovery of Phosphorylase Kinase with Ed Krebs he was clearly intrigued not only by cAMP‐dependent protein kinase (PKA), but also by the heat‐stable, high‐affinity protein kinase inhibitor (PKI).

A Systematic Evaluation of Protein Kinase A–A-Kinase Anchoring Protein Interaction Motifs
Protein kinase A (PKA) in vertebrates is localized to specific locations in the cell via A-kinase anchoring proteins (AKAPs). The regulatory subunits of the four PKA isoforms (RIα, RIβ, RIIα, and RIIβ) each form a homodimer, and their dimerization domain interacts with a small helical region present in each of the more than 40 AKAPs reported so far ...

Protein Kinase A: A Master Kinase of Granulosa Cell Differentiation [PDF]
AbstractActivation of protein kinase A (PKA) by follicle stimulating hormone (FSH) transduces the signal that drives differentiation of ovarian granulosa cells (GCs). An unresolved question is whether PKA is sufficient to initiate the complex program of GC responses to FSH.
