Abstract excerpt
Ca2 binding proteins such as calretinin, characterized by the presence of EF-hand motifs that bind Ca2+ ions, are involved in the shaping of intraneuronal Ca2+ fluxes. In the cerebellar cortex, information processing tightly relies on variations in intracellular Ca2+ concentration in Purkinje and granule cells. Calretinin-deficient (Cr-/-) mice present motor discoordination, suggesting cellular and network...
