The Ca2+/Calmodulin-dependent Protein Kinase Kinases Are AMP-activated Protein Kinase Kinases [PDF]

Journal of Biological Chemistry, 2005
The AMP-activated protein kinase (AMPK) is an important regulator of cellular metabolism in response to metabolic stress and to other regulatory signals. AMPK activity is absolutely dependent upon phosphorylation of AMPKalphaThr-172 in its activation loop by one or more AMPK kinases (AMPKKs).

A-kinase-anchoring proteins [PDF]

Journal of Cell Science, 2004
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 in Cancer [PDF]

Cancers, 2011
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.

Physiological Phosphorylation of Protein Kinase A at Thr-197 Is by a Protein Kinase A Kinase [PDF]

Molecular and Cellular Biology, 1998
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.

Metabolic Kinases Moonlighting as Protein Kinases [PDF]

Trends in Biochemical Sciences, 2018
Protein kinases regulate every aspect of cellular activity, whereas metabolic enzymes are responsible for energy production and catabolic and anabolic processes. Emerging evidence demonstrates that some metabolic enzymes, such as pyruvate kinase M2 (PKM2), phosphoglycerate kinase 1 (PGK1), ketohexokinase (KHK) isoform A (KHK-A), hexokinase (HK), and ...

A guanosine 5′-triphosphate-dependent protein kinase is localized in the outer envelope membrane of pea chloroplasts [PDF]

, 1988
A guanosine 5-triphosphate (GTP)-dependent protein kinase was detected in preparations of outer chloroplast envelope membranes of pea (Pisum sativum L.) chloroplasts.

A-kinase-interacting protein localizes protein kinase A in the nucleus [PDF]

Proceedings of the National Academy of Sciences, 2005
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)

The many-faced KSR1: a tumor suppressor in breast cancer [PDF]

, 2015
Emerging evidence supports the dual function of kinase suppressor of Ras 1 (KSR1) as an active kinase and a scaffold, although it has been extensively referred as a pseudokinase, due to the absence of key residues in its catalytic domain [1, 2].

Edmond Fischer's kinase legacy: History of the protein kinase inhibitor and protein kinase A

IUBMB Life, 2023
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).
