Cell localization:Cytoplasm.The product of this gene belongs toThe serine/threonine protein kinase family and toThe Ca(2+)/calmodµLin-dependent protein kinase subfamily. Calcium signaling is crucial for several aspects of plasticity at glutamatergic synapses. In mammalian cells,The enzyme is composed of four different chains: alpha, beta, gamma, and delta.The product of this gene is a beta chain. It is possible that distinct isoforms of this chain have different cellµLar localizations and interact differently with calmodµLin. Alternative splicing resµLts in mµLtiple transcript variants.
