General Information

General Information Comment Organism
evolution eEF2K is a calcium/calmodulin dependent kinase that belongs to the alpha kinase family, which has negligible sequence identity to the conventional protein kinase family Homo sapiens
additional information homology modelling of eEF2K using the structure of myosin heavy chain kinase, EC 2.7.11.7, PDB ID 3LMH. A glutamate might act as gatekeeper and makes likely hydrogen bonds to the adenine in the active site and is essential for activity in the alpha kinase family Homo sapiens
physiological function the phosphorylation of eEF2 through eEF2 kinase blocks translation elongation, which is thought to be critical to regulating cellular energy usage. eEF2K has a role in regulating cellular energy usage that involves multiple pathways and regulatory feedback Homo sapiens
