Acid Anhydride Hydrolases
Receptor, Adenosine A2A
An enzyme which catalyzes the hydrolysis of nucleoside triphosphates to nucleoside diphosphates. It may also catalyze the hydrolysis of nucleotide triphosphates, diphosphates, thiamine diphosphates and FAD. The nucleoside triphosphate phosphohydrolases I and II are subtypes of the enzyme which are found mostly in viruses.
Receptor, Adenosine A1
A subtype of ADENOSINE RECEPTOR that is found expressed in a variety of tissues including the BRAIN and DORSAL HORN NEURONS. The receptor is generally considered to be coupled to the GI, INHIBITORY G-PROTEIN which causes down regulation of CYCLIC AMP.
An enzyme that catalyzes the hydrolysis of ADENOSINE to INOSINE with the elimination of AMMONIA.
rac GTP-Binding Proteins
A sub-family of RHO GTP-BINDING PROTEINS that is involved in regulating the organization of cytoskeletal filaments. This enzyme was formerly listed as EC 220.127.116.11.
Receptor, Adenosine A3
A subtype of ADENOSINE RECEPTOR that is found expressed in a variety of locations including the BRAIN and endocrine tissues. The receptor is generally considered to be coupled to the GI, INHIBITORY G-PROTEIN which causes down regulation of CYCLIC AMP.
Receptor, Adenosine A2B
cdc42 GTP-Binding Protein
Receptors, Adenosine A2
A subclass of ADENOSINE RECEPTORS that are generally considered to be coupled to the GS, STIMULATORY G-PROTEIN which causes up regulation of CYCLIC AMP.
Adenosine A2 Receptor Agonists
Compounds that selectively bind to and activate ADENOSINE A2 RECEPTORS.
rho GTP-Binding Proteins
Adenosine A2 Receptor Antagonists
Compounds that selectively bind to and block the activation of ADENOSINE A2 RECEPTORS.
Receptors, Purinergic P1
A class of cell surface receptors that prefer ADENOSINE to other endogenous PURINES. Purinergic P1 receptors are widespread in the body including the cardiovascular, respiratory, immune, and nervous systems. There are at least two pharmacologically distinguishable types (A1 and A2, or Ri and Ra).
Adenosine A1 Receptor Antagonists
Compounds that bind to and block the stimulation of ADENOSINE A1 RECEPTORS.
rac1 GTP-Binding Protein
A rac GTP-binding protein involved in regulating actin filaments at the plasma membrane. It controls the development of filopodia and lamellipodia in cells and thereby influences cellular motility and adhesion. It is also involved in activation of NADPH OXIDASE. This enzyme was formerly listed as EC 18.104.22.168.
Adenosine A1 Receptor Agonists
Compounds that bind to and stimulate ADENOSINE A1 RECEPTORS.
Purinergic P1 Receptor Antagonists
Guanine Nucleotide Exchange Factors
Encyclopedias as Topic
Multisubunit enzymes that reversibly synthesize ADENOSINE TRIPHOSPHATE. They are coupled to the transport of protons across a membrane.
An enzyme that catalyzes the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane ATPase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients.
