Intracellular calcium signaling is involved in regulating the key functional mechanisms of the nervous system. The control of neuronal excitability and plasticity by calcium ions underlies the mechanisms of higher nervous activity, and the mechanisms of this control are of particular interest to researchers. A family of highly specialized neuronal proteins described in recent decades can translate the information contained in calcium signals into the regulation of channels, enzymes, receptors, and transcription factors. Neuronal calcium sensor-1 (NCS-1) is the most common member of the family, which is intensely expressed in central nervous system (CNS) cells; and controls several vital processes, such as neuronal growth and survival, reception, neurotransmission, and synaptic plasticity. In addition to calcium ions, NCS-1 can bind the so-called mobile, or signaling intracellular zinc, an increased concentration of which is a characteristic feature of cells in oxidative stress. Zinc coordination under these conditions stimulates NCS-1 oxidation to form a disulfide dimer (dNCS-1) with altered functional properties. A combined effect of mobile zinc and an increased redox potential of the medium can thus induce aberrant NCS-1 activity, including signals that promote survival of neuronal cells or induce their apoptosis and, consequently, the development of neurodegenerative processes. The review details the localization, expression regulation, structure, and molecular properties of NCS-1 and considers the current data on its signaling activity in health and disease, including zinc-dependent redox regulation cascades.
