Bestrophin-1 is a protein that, in humans, is encoded by the BEST1 gene (RPD ID - 5T5N/4RDQ).[5][6][7]
The bestrophin family is comprised of four ancestrally linked genes (BEST1, BEST2, BEST3, and BEST4) that code for integral membrane proteins.[8] The bestrophins were first identified in humans by relating a BEST1 mutation with Best vitelliform macular dystrophy (BVMD).[9] Mutations in the BEST1 gene have been determined as the primary cause for at least five different degenerative retinal diseases.[9]
Structure in humans
Gene structure
The bestrophin genes share a conserved gene structure, with almost identical sizes of the 8 RFP-TM domain-encoding exons and highly conserved exon-intron boundaries. Each of the 4 bestrophin genes has a unique 3-prime end of variable length.[7][10][11]
BEST1 has been shown by two independent studies to be regulated by Microphthalmia-associated transcription factor.[12][13]
Protein structure
Bestrophin 1 is an integral membrane protein found only in the retinal pigment epithelium (RPE) of the eye.[14] Within the RPE layer, Best1 is primarily located on the basolateral plasma membrane. Protein crystallization structures indicate the primary ion channel function of Best1 as well as the calcium regulatory capabilities.[14][15]Bestrophin 1 consists of 585 amino acids and both N- and the C-termini are located within the cell.
The structure of Best1 consists of five identical subunits that each span the membrane four times and form a continuous, funnel-shaped pore via the second transmembrane domain.[15][16] The pore is lined with various nonpolar, hydrophobic amino acids which help to act as a selectivity filter by forming at least 15 binding sites for each anion.[15][17] Both the structure and the composition of the pore help to ensure that only small anions are able to move completely through the channel. The channel acts as two funnels working together in tandem. It begins with a semi-selective, narrow entryway for anions, and then opens to a larger, positively charged area which then leads to a narrower pathway that further limits the size of anions passing through the pore. A calcium clasp acts as a belting mechanism around the larger, middle section of the channel. Calcium ions control the opening and closing of the channel due to conformational changes caused by calcium binding at the C-terminus directly following the last transmembrane domain.[15][16] The structure of the calcium-dependent chloride channel, which is bestrophin 1, contributes greatly to the overall function of the channel.[15]
Function
BEST1 belongs to the bestrophin family of calcium-activated anion channels, which includes BEST2, BEST3, and BEST4. Bestrophins are transmembrane (TM) proteins that share a homology region containing a high content of aromatic residues, including an invariant arg-phe-pro (RFP) motif. Bestrophins are believed to function as chloride channels that may also serve as regulators of intracellular calcium signalling.[18]
Interactions
Bestrophin 1 has been shown to interact with PPP2CA.[19][1]
