| | 4930433I11Rik | RIKEN cDNA 4930433I11 gene. (632 aa) |
| | Pde7b | cAMP-specific 3',5'-cyclic phosphodiesterase 7B; Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. May be involved in the control of cAMP-mediated neural activity and cAMP metabolism in the brain. (498 aa) |
| | Adcy7 | Adenylate cyclase type 7; Catalyzes the formation of cAMP in response to activation of G protein-coupled receptors (Probable). Functions in signaling cascades activated namely by thrombin and sphingosine 1-phosphate and mediates regulation of cAMP synthesis through synergistic action of the stimulatory G alpha protein with GNA13. Also, during inflammation, mediates zymosan-induced increase intracellular cAMP, leading to protein kinase A pathway activation in order to modulate innate immune responses through heterotrimeric G proteins G(12/13). Functions in signaling cascades activated n [...] (1099 aa) |
| | Ak9 | Adenylate kinase 9. (1894 aa) |
| | Nudt22 | Uridine diphosphate glucose pyrophosphatase NUDT22; Hydrolyzes UDP-glucose to glucose 1-phosphate and UMP and UDP-galactose to galactose 1-phosphate and UMP. Preferred substrate is UDP-glucose. (308 aa) |
| | Entpd4 | Ectonucleoside triphosphate diphosphohydrolase 4; Hydrolyzes preferentially nucleoside 5'-diphosphates, nucleoside 5'-triphosphates are hydrolyzed only to a minor extent. Belongs to the GDA1/CD39 NTPase family. (613 aa) |
| | Gucy1a1 | Guanylate cyclase soluble subunit alpha-1; Belongs to the adenylyl cyclase class-4/guanylyl cyclase family. (691 aa) |
| | Pde2a | cGMP-dependent 3',5'-cyclic phosphodiesterase; Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes. (945 aa) |
| | Olfr205 | Olfactory receptor. (305 aa) |
| | Nudt14 | Uridine diphosphate glucose pyrophosphatase NUDT14; Hydrolyzes UDP-glucose to glucose 1-phosphate and UMP and ADP-ribose to ribose 5-phosphate and AMP. The physiological substrate is probably UDP-glucose. Poor activity on other substrates such as ADP- glucose, CDP-glucose, GDP-glucose and GDP-mannose (By similarity). (222 aa) |
| | Sirt5 | NAD-dependent protein deacylase sirtuin-5, mitochondrial; NAD-dependent lysine demalonylase, desuccinylase and deglutarylase that specifically removes malonyl, succinyl and glutaryl groups on target proteins. Activates CPS1 and contributes to the regulation of blood ammonia levels during prolonged fasting: acts by mediating desuccinylation and deglutarylation of CPS1, thereby increasing CPS1 activity in response to elevated NAD levels during fasting. Activates SOD1 by mediating its desuccinylation, leading to reduced reactive oxygen species (By similarity). Activates SHMT2 by mediating [...] (310 aa) |
| | Nmrk1 | Nicotinamide riboside kinase 1; Catalyzes the phosphorylation of nicotinamide riboside (NR) and nicotinic acid riboside (NaR) to form nicotinamide mononucleotide (NMN) and nicotinic acid mononucleotide (NaMN). (195 aa) |
