Human Bestrophin 1 (BEST1) interaction partners

  1. Nuclear spheres modulate the expression of BEST1 and GADD45G (show GADD45G Proteins)

  2. Progressive posterior chorioretinal changes occurred over time in the initial ADVIRC proband, leading to visual loss. The causative mutation in this patient falls in the transmembrane domain of the BEST1 protein, with unclear functional consequences.

  3. HEK293T cells transfected with the identified BEST1 mutant showed significantly small currents compared to those transfected with the wild-type gene, whereas cells cotransfected with mutant and wild-type BEST1 showed good chloride conductance

  4. Bestrophin 1 is indispensable for volume regulation in human retinal pigment epithelium cells.

  5. We describe a novel mutation within the BEST1 gene of the heterozygous form giving rise to vitelliform lesions and secondary neovascularization successfully treated in a child with a course of bevacizumab.

  6. Dysfunction of bestrophin 1 may result in abnormal ion and fluid transport by the retinal pigment epithelium (RPE (show RPE Proteins)) disturbing and even disrupting direct interactions between the RPE (show RPE Proteins) and the photoreceptors.

  7. Two novel BEST1 mutations and associated clinical observations have been found in two unrelated patients with Best vitelliform macular dystrophy.

  8. Genetic sequence analysis of BEST1 is important in the diagnosis of Best vitelliform dystrophy, particularly in unusual cases, and helps to further our knowledge and understanding of this disease.

  9. Best1 I366fsX18 differs from Best1 in that it lacks most of the cytosolic C-terminal domain, suggesting that the loss of this region contributes significantly to the pathogenesis of ARB in this patient.

  10. Three novel BEST1 mutations are described, suggesting that many deleterious variants in BEST1 resulting in haploinsufficiency are still unknown.

Mouse (Murine) Bestrophin 1 (BEST1) interaction partners

  1. Data suggest that the ion channels CaV1.3 (show CACNA1D Proteins), bestrophin-1 and maxiK (show KCNMA1 Proteins) were identified as players in the regulation of photoreceptor outer segments (POS) phagocytosis by the retinal pigment epithelium (RPE (show RPE Proteins)).

  2. Best1-mediated astrocytic glutamate (show GRIN1 Proteins) activates the synaptic N-methyl-D-aspartate receptor (show GRIN1 Proteins) (NMDAR (show GRIN1 Proteins)) and modulates NMDAR (show GRIN1 Proteins)-dependent synaptic plasticity.

  3. Bestrophin-1 functions as an intracellular Cl channel which helps to accumulate and to release Ca(2 (show CA2 Proteins)+) from stores by conducting the counterion for Ca(2 (show CA2 Proteins)+).

  4. Best1, located at the microdomains near the synaptic junctions, has a significantly high permeability to glutamate (show GRIN1 Proteins) in vivo.

  5. Results show that different mutations in Best1 cause differential effects on its localization and that this effect varies with the presence or absence of wild-type (WT) Best1.

  6. Astrocytic glutamate (show GRIN1 Proteins) via Best1 channel targets and activates synaptic NMDA receptors.

  7. Upon activation of protease activated receptor 1 (PAR1 (show F2R Proteins)), an increase in intracellular Ca2 (show CA2 Proteins)+ concentration leads to an opening of Best1 channels and subsequent release of glutamate (show GRIN1 Proteins) in cultured astrocytes.

  8. Ultrastructural analyses demonstrate that TREK-1 (show KCNK2 Proteins) is preferentially localized at cell body and processes, whereas Best1 is mostly found in microdomains of astrocytes near synapses.

  9. study reports that tonic inhibition in the cerebellum is due to GABA being released from glial cells by permeation through the Bestrophin 1 anion channel

  10. SOX9 (show SOX9 Proteins), through interaction with microphthalmia-associated transcription factor (MITF (show MITF Proteins)) and OTX2 (show OTX2 Proteins), regulates BEST1 expression in the retinal pigment epithelium.

Pig (Porcine) Bestrophin 1 (BEST1) interaction partners

  1. Bestrophin-1 knock-down increases phagocytosis in primary porcine RPE (show RPE Proteins) cells.

  2. Retinal pigment epithelium bestrophin-1 possibly conducts Cl(-) as counter ion for Ca(2 (show CA2 Proteins)+) uptake into cytosolic Ca(2 (show CA2 Proteins)+) stores.

  3. examined the quaternary structure of native best-1 and found that it migrates as a single species with a Stokes radius of 7.3 nm, sedimentation coefficient (S20 (show RPS20 Proteins),w) of 4.9, and partial specific volume (nu) of 0.80 ml/g

Bestrophin 1 (BEST1) Protein Profile

Protein Summary

This gene encodes a member of the bestrophin gene family. This small gene family is characterized by proteins with a highly conserved N-terminus with four to six transmembrane domains. Bestrophins may form chloride ion channels or may regulate voltage-gated L-type calcium-ion channels. Bestrophins are generally believed to form calcium-activated chloride-ion channels in epithelial cells but they have also been shown to be highly permeable to bicarbonate ion transport in retinal tissue. Mutations in this gene are responsible for juvenile-onset vitelliform macular dystrophy (VMD2), also known as Best macular dystrophy, in addition to adult-onset vitelliform macular dystrophy (AVMD) and other retinopathies. Alternative splicing results in multiple variants encoding distinct isoforms.
