AC6, or Adenylate cyclase 6, is a human gene encoded by ADCY6. It may also be known as: Adenylate cyclase type 6; ATP pyrophosphate-lyase 6; Adenylate cyclase type VI; Adenylyl cyclase 6; Ca(2+)-inhibitable adenylyl cyclase; Adenylate cyclase type 6 . The encoded protein is an enzyme with an amino acid length of 1168 and a mass of 130.6 kDa. AC6 is a member of the Adenylyl cyclase class-4/guanylyl cyclase family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog.
