Adenylate Cyclase 2, Brain (ADCY2)

Adenylate cyclase type 2 is a member of the family of adenylate cyclases, which are membrane-associated enzymes that catalyze the formation of the secondary messenger cyclic adenosine monophosphate (cAMP). This enzyme is insensitive to Ca(2+)/calmodulin, and is stimulated by the G protein beta and gamma subunit complex.

The amino acid sequence of ADCY2 displayed significant homology with ADCY8 in the highly conserved adenylyl cyclase domain (250 amino acids) found in the 3-prime cytoplasmic portion of all mammalian adenylyl cyclases. However, outside this domain, the homology was extremely low.Semiquantitative RT-PCR detected ADCY2 in all tissues examined except peripheral blood leukocytes. Highest expression was detected in brain, skeletal muscle, and testis.
