General annotation (Comments)
| Function | Calcium/calmodulin-dependent protein kinase belonging to a proposed calcium-triggered signaling cascade involved in a number of cellular processes. Phosphorylates CAMK1, CAMK4 and CAMK1D By similarity. Efficiently phosphorylates 5'-AMP-activated protein kinase (AMPK) trimer, including that consisting of PRKAA1, PRKAB1 and PRKAG1. This phosphorylation is stimulated in response to Ca2+ signals By similarity. May play a role in neurite growth. Isoform 2 may promote neurite elongation, while isoform 1 may promoter neurite branching By similarity. May be involved in hippocampal activation of CREB1. Ref.5 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Enzyme regulation | Activated by Ca2+/calmodulin. Binding of calmodulin may relieve intrasteric autoinhibition. Autophosphorylation does not alter activity or regulation by Ca2+/calmodulin. In part, activity is independent on Ca2+/calmodulin By similarity. |
| Subunit structure | Interacts with calmodulin By similarity. |
| Subcellular location | Nucleus By similarity. Cytoplasm By similarity. Cell projection By similarity. Note: Predominantly nuclear in unstimulated cells By similarity. Found in the cytoplasm and neurites after forskolin induction By similarity. |
| Tissue specificity | Expressed in all tissues tested. A differential expression pattern compared to CAMKK1 is observed in the brain. Ref.1 |
| Domain | The autoinhibitory domain overlaps with the calmodulin binding region and may be involved in intrasteric autoinhibition. The RP domain (arginine/proline-rich) is involved in the recognition of CAMKI and CAMK4 as substrates By similarity. |
| Post-translational modification | Autophosphorylated and phosphorylated by PKA By similarity. Each isoform may show a different pattern of phosphorylation By similarity. |
| Disruption phenotype | Mice are unable to form spatial long-term memory. Ref.5 |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 1 protein kinase domain. |
