Background of Bestrophin-1 antibody

Mammalian Cl channels can be broadly classified into four different families: voltage-dependent Cl channels (CLCs), the cystic fibrosis transmembrane conductance regulator (CFTR), ligand-gated Cl channels (?-aminobutyric acid (GABA)) and glycine channels) and Ca2+-activated Cl channels (Bestrophin and Anoctamin channels). Bestrophins were first found by genetic linkage of human-Bestrophin-1 (hBest1) to a juvenile form of macular degeneration called Best vitelliform macular dystrophy (BVMD). BVMD is mainly electrophysiologically characterized by a decrease in the light peak and physiologically by the thinning of the reti layer which eventually leads to the loss of central vision. To date Bestrophin 1-4 have been identified, although Bestrophin-3 and Bestrophin-4 have been observed only at the R level. In addition, splice variants of some of these Ca2+-activated Cl channels (CaCCs) have also been detected. CaCCs are known to be involved in the regulation of olfaction, taste, phototransduction, and excitability in the nervous system. Recently, Bestrophin-1 was shown to be functiolly expressed in astrocytes in both primary cell culture and in situ. Bestrophin-1 is also detected in reti, brain, spil cord and testes. Two different topologies for Bestrophin-1 have been proposed. The first, the preferred structure, proposes that six hydrophobic domains span the membrane, while the second suggests that there are only four membrane-spanning domains. Bestrophin-1, along with its counterparts, is activated by intracellular Ca2+. A recent study demonstrated that Bestrophin-1 indeed binds Ca2+ and by mutating specific residues, showed which amino acid residues are essential for binding Ca2+, providing additiol evidence that Bestrophin-1 is activated by direct binding of Ca2+ to the channel. Bestrophin-1 has been found to release glutamate from astrocytes and is located at microdomains near sypses.
