Protein attributes
| Sequence length | 898 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | May regulate transmembrane proteins that bind calcium, calmodulin, or nucleotides. Functionally modulates eag potassium channels; increases eag current and whole-cell conductance. Also regulates autophosphorylation of CaMKII. Ref.7 Ref.8 Ref.9 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Subunit structure | |
| Subcellular location | Cell membrane; Peripheral membrane protein. Note: Eag recruits CASK to the plasma membrane. Ref.8 |
| Tissue specificity | During embryogenesis, larval and pupal life, found almost exclusively in the central nervous system. In the adult head found in the lamina, the neuropil of the medulla, lobula, lobula plate and in the central brain. Ref.2 |
| Disruption phenotype | Increases synapse-specific, activity-dependent autophosphorylation of CaMKII Thr-287. Ref.9 |
| Sequence similarities | In the N-terminal section; belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily. Belongs to the MAGUK family. Contains 1 guanylate kinase-like domain. Contains 2 L27 domains. Contains 1 PDZ (DHR) domain. Contains 1 protein kinase domain. Contains 1 SH3 domain. |
| Sequence caution | The sequence AAM11269.1 differs from that shown. Reason: Probable cloning artifact. The sequence AAO39536.1 differs from that shown. Reason: Frameshift at position 114. The sequence CAA63940.1 differs from that shown. Reason: Frameshift at positions 537 and 667. |
