アデニル酸シクラーゼ

Adenylate cyclase type 1

  • This is a calmodulin-sensitive adenylyl cyclase. May be involved in regulatory processes in the central nervous system. It may play a role in memory acquisition and learning.
Enzyme regulation
Activated by calcium/calmodulin. Inhibited by the G protein beta and gamma subunit complex.

type 2

  • This is a membrane-bound, calmodulin-insensitive adenylyl cyclase.
Cofactor
Binds 2 magnesium ions per subunit By similarity.
Enzyme regulation
Insensitive to calcium/calmodulin. Stimulated by the G protein beta and gamma subunit complex By similarity. Phosphorylation by RAF1 results in its activation. Ref.6
Subunit structure
Interacts with RAF1. Ref.6
Subcellular location
Membrane; Multi-pass membrane protein.
Tissue specificity
Expressed in brain.
Post-translational modification
Phosphorylated by RAF1.

type 3

  • Mediates odorant detection (possibly) via modulation of intracellular cAMP concentration.
Cofactor
Binds 2 magnesium ions per subunit By similarity.
Enzyme regulation
Activated by calcium/calmodulin.
Subcellular location
Membrane; Multi-pass membrane protein.
Tissue specificity
Expressed in brain, heart, kidney, liver, lung, pancreas, placenta, and skeletal muscle.
