CGK2 is an alias for the gene, Protein kinase, cGMP-dependent, type II, in humans. Other names include: cGMP-dependent protein kinase 2; cGK2; cGMP-dependent protein kinase II; cGKII; cGK 2; PRKGR2. The encoded protein is an enzyme with an amino acid length of 762 and a mass of 87.4 kDa. Other isoforms may exist. CGK2 is a member of the Protein kinase superfamily, AGC Ser/Thr protein kinase family, cGMP subfamily. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog, Chicken.
