About BEST2

Cytogenetic location: 19p13.13 Genomic coordinates (GRCh38): 19:12,751,791-12,758,458 (from NCBI)

This gene has 4 transcripts (splice variants), 202 orthologues and 3 paralogues. Restricted expression toward colon (RPKM 11.0).

Summary

This gene is a member of the bestrophin gene family of anion channels. Bestrophin genes share a similar gene structure with highly conserved exon-intron boundaries, but with distinct 3' ends. Bestrophins are transmembrane proteins that contain a homologous region rich in aromatic residues, including an invariant arg-phe-pro motif. Mutation in one of the family members (bestrophin 1) is associated with vitelliform macular dystrophy. The bestrophin 2 gene is mainly expressed in the retinal pigment epithelium and colon.
