A brain serine/threonine protein kinase activated by Cdc42 and Rac1
Nature, 1994A new brain serine/threonine protein kinase may be a target for the p21ras-related proteins Cdc42 and Rac1. The kinase sequence is related to that of the yeast protein STE20, implicated in pheromone-response pathways. The kinase complexes specifically with activated (GTP-bound) p21, inhibiting p21 GTPase activity and leading to kinase ...

RAF protein-serine/threonine kinases: Structure and regulation
Biochemical and Biophysical Research Communications, 2010A-RAF, B-RAF, and C-RAF are a family of three protein-serine/threonine kinases that participate in the RAS-RAF-MEK-ERK signal transduction cascade. This cascade participates in the regulation of a large variety of processes including apoptosis, cell cycle progression, differentiation, proliferation, and transformation to the cancerous state.

PkpA, a novel Phycomyces blakesleeanus serine/threonine protein kinase
Current Genetics, 1995This work reports the cloning and sequencing of pkpA, a gene of the filamentous fungus Phycomyces blakesleeanus, whose expression seems to be coupled to vegetative growth. This gene encodes a putative serine/threonine-specific protein kinase, whose sequence is related to that of the yeast protein STE20, involved in pheromone-response pathways, and to a

We report the molecular cloning and initial characterization of a novel fatty acid acylated serine/threonine protein kinase. The putative open reading frame is predicted to encode a 305 amino acid protein possessing a carboxy-terminal protein kinase domain and amino-terminal myristylation and palmitylation sites. The protein kinase has been accordingly

Inhibition of Eukaryote Serine/Threonine-Specific Protein Kinases by Piceatannol
Planta Medica, 1998The protein tyrosine kinase (PTK) inhibitor piceatannol is also an inhibitor of the rat liver cyclic AMP-dependent protein kinase (PKA) catalytic subunit (cAK), rat brain Ca(2+)- and phospholipid-dependent protein kinase C (PKC), avian gizzard Ca(2+)-calmodulin-dependent myosin light chain kinae (MLCK), and of wheat embryo Ca(2+)-dependent protein ...

Balanol is a potent inhibitor of cyclic AMP-dependent protein kinase and protein kinase C, acting competitively with ATP with an affinity 3000 times that of ATP. We tested the capacity of balanol to inhibit representative serine- and threonine-specific protein kinases from the protein kinase subfamily that shares a common conserved catalytic core with ...

Effect of Glucuronidation on the Potential of Kaempferol To Inhibit Serine/Threonine Protein Kinases
Journal of Agricultural and Food Chemistry, 2016To study the effect of metabolic conjugation of flavonoids on the potential to inhibit protein kinase activity, the inhibitory effects of the dietary flavonol kaempferol and its major plasma conjugate kaempferol-3-O-glucuronide on protein kinases were studied.

The inhibitory potencies of bioflavonoids on various tyrosine protein kinases and serine/threonine protein kinases were investigated. The phosphotransferase activity of an oncogene product, pp130fps, and a growth factor receptor, insulin receptor, were inhibited by myricetin, a derivative of quercetin.

Identification of a Putative Target for Rho as the Serine-Threonine Kinase Protein Kinase N
Science, 1996Rho, a Ras-like small guanosine triphosphatase, has been implicated in cytoskeletal responses to extracellular signals such as lysophosphatidic acid (LPA) to form stress fibers and focal contacts. The form of RhoA bound to guanosine triphosphate directly bound to and activated a serine-threonine kinase, protein kinase N (PKN).
