FORRELLAT BARRIOS, Mariela  and  HERNANDEZ RAMIREZ, Porfirio. Neuroglobin: a novel member of the globin family. Rev Cubana Hematol Inmunol Hemoter [online]. 2011, vol.27, n.3, pp. 291-296. ISSN 0864-0289.

For a long time, it was taken for granted that hemoglobin and mioglobin were the only vertebrate globins. In 2000, a third type of globins was discovered on the basis of its preferential location in the nervous system and it was called neuroglobin. Although its specific function is still unknown, a number of hypotheses has been put forward, mainly the one suggesting that it may detoxify the reactive oxygen species and the nitrogen. On the other hand, other studies state that neuroglobin is part of a signal transduction chain that transmits the redox state of the cell or inhibits apoptosis. Though some functions are more probable than others, the real physiological function of neuroglobin in vertebrae has not been finally established. Nevertheless, this globin has undoubtedly an essential preserved function that is useful for neurons.

Keywords : neuroglobin; globins; neuroprotection.
