CaMKII alpha/CAMK2A Protein, Human (Active, sf9, GST)

CaMKII α/CAMK2A protein functions autonomously upon Ca(2+)/calmodulin binding and autophosphorylation. CaMKII alpha/CAMK2A Protein, Human (sf9, GST) is the recombinant human-derived CaMKII alpha/CAMK2A protein, expressed by Sf9 insect cells , with N-GST labeled tag.

CaMKII alpha/CAMK2A protein, a calcium/calmodulin-dependent kinase, functions autonomously following Ca(2+)/calmodulin-binding and autophosphorylation, playing a crucial role in various cellular processes such as synaptic plasticity, neurotransmitter release, and long-term potentiation. As a member of the NMDAR signaling complex in excitatory synapses, it regulates NMDAR-dependent potentiation of the AMPAR, thereby influencing excitatory synaptic transmission. CaMKII alpha also contributes to dendritic spine development and regulates the migration of developing neurons. Beyond these functions, it phosphorylates the transcription factor FOXO3 to activate its transcriptional activity and targets the transcription factor ETS1 in response to calcium signaling, decreasing ETS1 affinity for DNA. In response to interferon-gamma (IFN-gamma) stimulation, it catalyzes the phosphorylation of STAT1, thereby stimulating the JAK-STAT signaling pathway. Additionally, in response to interferon-beta (IFN-beta) stimulation, CaMKII alpha stimulates the JAK-STAT signaling pathway and acts as a negative regulator of 2-arachidonoylglycerol (2-AG)-mediated synaptic signaling via modulation of DAGLA activity.

The specific activity was determined to be >100 nmol/min/mg using Autocamtide-2 synthetic peptide (KKALRRQETVDAL-amide) as substrate.
