Diacylglycerol kinase control of protein kinase C
Abstract The diacylglycerol kinases (DGK) are lipid kinases that transform diacylglycerol (DAG) into phosphatidic acid (PA) in a reaction that terminates DAG-based signals. DGK provide negative regulation to conventional and novel protein kinase C (PKC) enzymes, limiting local DAG availability in a tissue- and subcellular-restricted ...

Activation of tyrosine kinases by mutation of the gatekeeper threonine. [PDF]
Protein kinases targeted by small-molecule inhibitors develop resistance through mutation of the gatekeeper threonine residue of the active site. Here we show that the gatekeeper mutation in the cellular forms of c-ABL, c-SRC, platelet-derived growth ...

Phosphorylation by protein kinase C and the responsiveness of Mg2+-ATPase to Ca2+ of myofibrils isolated from stunned and non-stunned porcine myocardinm [PDF]
Previously we showed in an in situ porcine model that the thiadiazinone derivative [+]EMD 60263, a Ca2+ sensitizer without phosphodiesterase III inhibitory properties, increased contractility more profoundly in stunned than in non-stunned myocardium ...

Phosphorylation by Akt within the ST loop of AMPK-α1 down-regulates its activation in tumour cells [PDF]
The insulin/IGF-1 (insulin-like growth factor 1)-activated protein kinase Akt (also known as protein kinase B) phosphorylates Ser(487) in the ‘ST loop’ (serine/threonine-rich loop) within the C-terminal domain of AMPK-α1 (AMP-activated protein kinase-α1),

Phosphorylation of protein kinase C by casein kinase‐1 [PDF]
Because phosphorylation of protein kinase C (PKC) may provide a mechanism for regulation of this enzyme, we have examined the ability of two other kinases to phosphorylate PKC. Our results show that casein kinase 1 (CK‐1), but not casein kinase 2 (CK‐2), can phosphorylate PKC in the absence of Ca2+ and phospholipids.

IKKα negatively regulates ASC-dependent inflammasome activation. [PDF]
The inflammasomes are multiprotein complexes that activate caspase-1 in response to infections and stress, resulting in the secretion of pro-inflammatory cytokines.

Familial HDL deficiency (FHD) is the heterozygous form of Tangier disease (TD). Mutations of the ABCA1 gene cause FHD and TD. FHD/TD cells are unable to normally efflux cholesterol onto nascent HDL particles, which are rapidly catabolized. TD fibroblasts

Protein kinase C and human uterine contractility
Abnormalities in uterine contractility are thought to contribute to several clinical problems, including preterm labor. A better understanding of the mechanisms controlling uterine activity would make it possible to propose more appropriate and effective
