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. (From Merck Index, 11th ed). 3',5'-cyclic GMP : A 3',5'-cyclic purine nucleotide in which the purine nucleobase is specified as guanidine. | 3.97 | 4 | 0 | 3',5'-cyclic purine nucleotide; guanyl ribonucleotide | Escherichia coli metabolite; human metabolite; mouse metabolite; plant metabolite; Saccharomyces cerevisiae metabolite |
guanylyl imidodiphosphate Guanylyl Imidodiphosphate: A non-hydrolyzable analog of GTP, in which the oxygen atom bridging the beta to the gamma phosphate is replaced by a nitrogen atom. It binds tightly to G-protein in the presence of Mg2+. The nucleotide is a potent stimulator of ADENYLYL CYCLASES.. guanosine 5'-[beta,gamma-imido]triphosphate : A nucleoside triphosphate analogue that is GTP in which the oxygen atom bridging the beta- to the gamma- phosphate is replaced by a nitrogen atom A non-hydrolyzable analog of GTP, it binds tightly to G-protein in the presence of Mg(2+). | 1.95 | 1 | 0 | nucleoside triphosphate analogue | |

concanavalin a Concanavalin A: A MANNOSE/GLUCOSE binding lectin isolated from the jack bean (Canavalia ensiformis). It is a potent mitogen used to stimulate cell proliferation in lymphocytes, primarily T-lymphocyte, cultures. | 3.06 | 5 | 0 | | |
leptin Leptin: A 16-kDa peptide hormone secreted from WHITE ADIPOCYTES. Leptin serves as a feedback signal from fat cells to the CENTRAL NERVOUS SYSTEM in regulation of food intake, energy balance, and fat storage. | 7.01 | 1 | 0 | | |
