Calcium-binding proteins in whole brain and synaptic subfractions.
At least 19 calcium-binding proteins were detected in avian brain subfraction using 45Ca2+ binding to proteins immobilized in polyacrylamide gels. Half of the 45Ca2+ binding proteins were observed in presynaptic cytoplasm. Two-dimensional gel electrophoresis of this material revealed at least 14 45Ca2+ binding polypeptides besides calmodulin. These proteins may be important in brain and nerve terminal function.
