CAMK2A phospho T286

Function

Calcium/calmodulin-dependent protein kinase that functions autonomously after Ca(2+)/calmodulin-binding and autophosphorylation, and is involved in various processes, such as synaptic plasticity, neurotransmitter release and long-term potentiation (PubMed:14722083). Member of the NMDAR signaling complex in excitatory synapses, it regulates NMDAR-dependent potentiation of the AMPAR and therefore excitatory synaptic transmission (By similarity). Regulates dendritic spine development (PubMed:28130356). Also regulates the migration of developing neurons (PubMed:29100089). Phosphorylates the transcription factor FOXO3 to activate its transcriptional activity (PubMed:23805378). Phosphorylates the transcription factor ETS1 in response to calcium signaling, thereby decreasing ETS1 affinity for DNA (By similarity). In response to interferon-gamma (IFN-gamma) stimulation, catalyzes phosphorylation of STAT1, stimulating the JAK-STAT signaling pathway (PubMed:11972023). In response to interferon-beta (IFN-beta) stimulation, stimulates the JAK-STAT signaling pathway (PubMed:35568036). Acts as a negative regulator of 2-arachidonoylglycerol (2-AG)-mediated synaptic signaling via modulation of DAGLA activity (By similarity).

Involvement in disease

Intellectual developmental disorder, autosomal dominant 53

MRD53

A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period.

None

The disease is caused by variants affecting the gene represented in this entry.

Intellectual developmental disorder, autosomal recessive 63

MRT63

A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRT63 patients manifest global developmental delay, severe intellectual disability, and seizures.

None

The disease is caused by variants affecting the gene represented in this entry.

Post-translational modifications

Autophosphorylation of Thr-286 following activation by Ca(2+)/calmodulin. Phosphorylation of Thr-286 locks the kinase into an activated state.

Palmitoylated. Probably palmitoylated by ZDHHC3 and ZDHHC7.
