Bestrophin3 Deficiency in Vascular Smooth Muscle Cells Activates MEKK2/3-MAPK Signaling to Trigger Spontaneous Aortic Dissection.
Title: Bestrophin3 Deficiency in Vascular Smooth Muscle Cells Activates MEKK2/3-MAPK Signaling to Trigger Spontaneous Aortic Dissection.
The authors propose that Best3V2 isoform in myoblasts may work as a tuner to control Ca(2+) release from intracellular Ca(2+) stores.
Title: A C-terminally truncated mouse Best3 splice variant targets and alters the ion balance in lysosome-endosome hybrids and the endoplasmic reticulum.
Our experiments present clear evidence of Best3 mRNA and protein expression in mouse kidney glomeruli
Title: Bestrophin-3 is differently expressed in normal and injured mouse glomerular podocytes.
results demonstrated that Best-3 is an endogenous inhibitor of NF-kappaB signaling pathway in endothelial cells, suggesting that forced Best-3 expression may be a novel approach for the treatment of vascular inflammatory diseases.
Title: Bestrophin 3 ameliorates TNFα-induced inflammation by inhibiting NF-κB activation in endothelial cells.
These results suggest that an auto-inhibitory mechanism in C termini of bestrophin 3 may be universal among bestrophins investigated in the study.
Title: Activation of bestrophin Cl- channels is regulated by C-terminal domains.
The channel activity of the mBest4 protein lacking the C-terminus (residues 353-669) was specifically inhibited by co-expression of C-terminal fragments of mBest4 having the inhibitory motif.
Title: A short motif in the C-terminus of mouse bestrophin 3 [corrected] inhibits its activation as a Cl channel.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
