Phospho-CaMK2 beta/gamma/delta (Thr287) Antibody detects endogenous levels of CaMK2 beta/gamma/delta only when phosphorylated at Threonine 287. The product of this gene belongs to the serine/threonine protein kinase family and to the Ca (2+)/calmodulin-dependent protein kinase subfamily. Calcium signaling is crucial for several aspects of plasticity at glutamatergic synapses.
