Specific binding proteins for cyclic AMP and cyclic GMP in Dictyostelium discoideum. 1978

H J Rahmsdorf, and G Gerisch

In Dictyostelium discoideum both cyclic AMP and cyclic GMP are regulated by chemotactic stimuli. Binding proteins specific for cAMP and cGMP have been found in aggregation competent cells as well as in cells harvested during growth. The activity of binding proteins was, on the average, lower in the growth phase cells. cAMP binding proteins were separated into 3 fractions, whereas the cGMP binding activity appeared in 1 major peak both on DEAE-cellulose and Sephadex G-200. Protein kinase activity was present in most but not all cyclic necleotide binding fractions; evidence for a relationship is however missing.

UI	MeSH Term	Description	Entries
D011494	Protein Kinases	A family of enzymes that catalyze the conversion of ATP and a protein to ADP and a phosphoprotein.	Protein Kinase,Kinase, Protein,Kinases, Protein
D011953	Receptors, Cyclic AMP	Cell surface proteins that bind cyclic AMP with high affinity and trigger intracellular changes which influence the behavior of cells. The best characterized cyclic AMP receptors are those of the slime mold Dictyostelium discoideum. The transcription regulator CYCLIC AMP RECEPTOR PROTEIN of prokaryotes is not included nor are the eukaryotic cytoplasmic cyclic AMP receptor proteins which are the regulatory subunits of CYCLIC AMP-DEPENDENT PROTEIN KINASES.

D002453	Cell Cycle	The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.

D004023	Dictyostelium	A genus of protozoa, formerly also considered a fungus. Its natural habitat is decaying forest leaves, where it feeds on bacteria. D. discoideum is the best-known species and is widely used in biomedical research.	Dictyostelium discoideum,Dictyostelium discoideums,Dictyosteliums,discoideum, Dictyostelium
D006152	Cyclic GMP	Guanosine cyclic 3',5'-(hydrogen phosphate). A guanine nucleotide containing one phosphate group which is esterified to the sugar moiety in both the 3'- and 5'-positions. It is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin and it has been found to activate specific protein kinases.
