Description
BACKGROUNDĀ Calbindin D belongs to the EF-hand family of calcium binding proteins and binds calcium ion with a fast association rate. It is widely expressed in Ca2+ transporting tissues such as epithelial-absorptive cells of the intestine and the distal tubular epithelial cells of the kidney. Calbindin-D was also found in the nervous system and it was suggested to co-localize with plasma membrane Ca2+ pumps. The function of Calbindin-D is dependent on the intracellular Ca2+ concentrations and it was shown that Ca2+ binding to Calbindin-D induced local structure changes around aromatic residues while no significant secondary structural changes were observed. In addition, Calbindin-D-containing neurons are thought to be related with memory, learning and long-term potentiation.1 It has been well known that Ca2+ plays a critical role in the light-mediated resetting of the circadian clock. Calbindin D influences Ca2+ buffering capacity of a cell, alters spatio-temporal aspects of intracellular Ca2+ signaling, and hence alters transmission of light information to the circadian clock in neurons of the suprachiasmatic nuclei (SCN).2 Moreover, Calbindin-D was also implicated in Parkinsonās disease (PD) since it was found that the dopaminergic neurons of the substantia nigra pars compacta (A9) expressing calbindin-D were more resistant to cell death than the neurons that do not express Calbindin-D in PD and in animal. In addition, alpha-Synuclein is a natively unfolded protein aggregation which is implicated in the pathogenesis of PD and several other neurodegenerative diseases, is known to interact with a great number of unrelated proteins. Some of these proteins, such as beta-synuclein and DJ-1, were shown to inhibit alpha-synuclein aggregation in vitro and in vivo therefore acting as chaperones. It was shown that Calbindin-D is also able to interact and co-aggregate with alpha-synuclein, significantly inhibiting alpha-synuclein fibrillation. Therefore, Calbindin-D28K can act as a chaperone, efficiently suppressing the process of alpha-synuclein fibril formation.3
