Function

Ligand-gated anion channel that allows the movement of anions across cell membranes when activated by calcium (Ca2+) (PubMed:11904445, PubMed:12907679, PubMed:18179881, PubMed:18400985, PubMed:19853238, PubMed:21330666, PubMed:26200502, PubMed:26720466, PubMed:35789156). Allows the movement of chloride and hydrogencarbonate (PubMed:11904445, PubMed:12907679, PubMed:18179881, PubMed:18400985, PubMed:19853238, PubMed:21330666, PubMed:26200502, PubMed:26720466, PubMed:35789156). Found in a partially open conformation leading to significantly smaller chloride movement (PubMed:35789156). Upon F2R/PAR-1 activation, the sequestered calcium is released into the cytosol of astrocytes, leading to the (Ca2+)-dependent release of L-glutamate into the synaptic cleft that targets the neuronal postsynaptic GRIN2A/NMDAR receptor resulting in the synaptic plasticity regulation (By similarity). Upon activation of the norepinephrine-alpha-1 adrenergic receptor signaling pathway, transports as well D-serine than L-glutamate in a (Ca2+)-dependent manner, leading to activation of adjacent NMDAR receptors and therefore regulates the heterosynaptic long-term depression and metaplasticity during initial memory acquisition (By similarity). Releases the 4-aminobutanoate neurotransmitter in a (Ca2+)-dependent manner, and participates in its tonic release from cerebellar glial cells (By similarity).

Activity summary

Bestrophin also known as BEST1 or VMD2 is a protein that functions as a calcium-activated chloride channel. It plays an important role in the transport of ions across cell membranes. The molecular mass of BEST1 is about 68 kDa. This protein is prominently expressed in the retinal pigment epithelium (RPE) which is a layer of cells in the eye vital to the function and survival of the photoreceptors. These photoreceptors are responsible for capturing light and initiating vision.

Biological function summary

BEST1 influences the regulation of ionic homeostasis in the eye and contributes to the RPE's maintenance. It acts as part of a chloride channel complex that helps transport chloride ions which is important for fluid absorption and secretion in the retina. There are interactions with calcium ions that activate the channel allowing it to regulate the flow of other ions in response to changes in calcium concentration which is essential for maintaining the ionic balance necessary for proper vision.

Pathways

BEST1 plays significant roles in the visual cycle and ion transport pathways in the retina. It is related to the protein ANO2 another chloride channel although they interact differently with calcium ions. BEST1 influences the fluid regulation within the retina an essential part of the visual cycle pathway. It signals the movement of ions in response to external stimuli maintaining the balance of fluids and ions that reh cells function correctly.

Associated diseases and disorders

Mutations in the BEST1 gene are connected to Best vitelliform macular dystrophy and adult-onset foveomacular dystrophy. Both disorders lead to retinal degeneration affecting vision. The interaction between BEST1 and other chloride channels like ANO2 suggests possible effects on the severity and progression of these retinal diseases highlighting the need for continued research into therapeutic interventions and the complex network of protein interactions within the retina.

    Immunohistochemistry (Frozen sections) - Anti-Bestrophin/BEST1 antibody [EPR23926-112] (ab259836)

    IHC image of BEST1 staining in a section of frozen normal human hippocampus* performed on a Leica BOND™ system using the standard protocol. The section was fixed in 10% paraformaldehyde (10 min) prior to staining. The section was incubated with ab259836, 0.1μg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
