Disappearance of Ca2+-sensitive, phospholipid-dependent protein kinase activity in phorbol ester-treated 3T3 cells. 1984

A Rodriguez-Pena, and E Rozengurt

Treatment of intact 3T3 cells with biologically active phorbol esters causes a progressive decline in the total activity of Ca2+-sensitive, phospholipid-dependent protein kinase (protein kinase C) measured in cell-free, detergent-solubilized, extracts. The effect is dose-dependent and reversible; protein kinase C activity reappears when the phorbol esters are removed from the medium.

D010703	Phorbol Esters	Tumor-promoting compounds obtained from CROTON OIL (Croton tiglium). Some of these are used in cell biological experiments as activators of protein kinase C.	Phorbol Diester,Phorbol Ester,Phorbol Diesters,Diester, Phorbol,Diesters, Phorbol,Ester, Phorbol,Esters, Phorbol
D010704	Phorbols	The parent alcohol of the tumor promoting compounds from CROTON OIL (Croton tiglium).	Tigliane,Tiglianes
D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.	Phosphatides,Phospholipid
D011493	Protein Kinase C	An serine-threonine protein kinase that requires the presence of physiological concentrations of CALCIUM and membrane PHOSPHOLIPIDS. The additional presence of DIACYLGLYCEROLS markedly increases its sensitivity to both calcium and phospholipids. The sensitivity of the enzyme can also be increased by PHORBOL ESTERS and it is believed that protein kinase C is the receptor protein of tumor-promoting phorbol esters.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015240	Phorbol 12,13-Dibutyrate	A phorbol ester found in CROTON OIL which, in addition to being a potent skin tumor promoter, is also an effective activator of calcium-activated, phospholipid-dependent protein kinase (protein kinase C). Due to its activation of this enzyme, phorbol 12,13-dibutyrate profoundly affects many different biological systems.	Phorbol-12,13-Dibutyrate,12,13-Dibutyrate, Phorbol,Phorbol 12,13 Dibutyrate
