| Tissue Specificity | Abundantly expressed in atrial myocardium (at protein level). Expressed in lung fibroblasts, cervical epithelial and B-cells (at protein level). Expressed in the brain (at protein level). Widely expressed, with isoforms displaying different expression profiles. |
| Post Translational Modifications | Phosphorylated by MAPK12. Phosphorylation of Ser-232 regulates association with GRIN2A. Ubiquitinated.by MARCHF2 which results in its degradation. |
| Function | Essential multidomain scaffolding protein required for normal development. Recruits channels, receptors and signaling molecules to discrete plasma membrane domains in polarized cells. Promotes epithelial cell layer barrier function via maintaining cell-cell adhesion. May also play a role in adherens junction assembly, signal transduction, cell proliferation, synaptogenesis and lymphocyte activation. Regulates the excitability of cardiac myocytes by modulating the functional expression of Kv4 channels. Functional regulator of Kv1.5 channel. During long-term depression in hippocampal neurons, it recruits ADAM10 to the plasma membrane. |
