Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Also known as: Vmd2
Summary: Predicted to enable bicarbonate channel activity; identical protein binding activity; and intracellularly calcium-gated chloride channel activity. Predicted to contribute to chloride channel activity. Predicted to be involved in several processes, including protein complex oligomerization; secretion by cell; and transepithelial chloride transport. Predicted to act upstream of or within chloride transport; detection of light stimulus involved in visual perception; and regulation of calcium ion transport. Predicted to be located in basolateral plasma membrane and membrane microdomain. Predicted to be part of chloride channel complex. Human ortholog(s) of this gene implicated in autosomal dominant vitreoretinochoroidopathy; bestrophinopathy; macular degeneration; retinitis pigmentosa 50; and vitelliform macular dystrophy. Orthologous to human BEST1 (bestrophin 1). [provided by Alliance of Genome Resources, Dec 2024]

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.
