ALPK3 encodes the human gene, Alpha kinase 3. It may also be known as: Alpha-protein kinase 3; Muscle alpha-protein kinase; Alpha-protein kinase 3 ; myocyte induction differentiation originator; muscle alpha-kinase; MIDORI; alpha-kinase 3. The encoded protein is an enzyme with an amino acid length of 1907 and a mass of 201.3 kDa. Other isoforms may exist. ALPK3 is a member of the Protein kinase superfamily, Alpha-type protein kinase family, ALPK subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Chicken.
