This locus likely encodes a transmembrane protein that may function as a riboflavin transporter. Mutations at this locus have been associated with Brown-Vialetto-Van Laere syndrome. [provided by RefSeq, Sep 2010].
Function: Riboflavin transporter. Riboflavin transport is Na(+)-independent but moderately pH-sensitive. Activity is strongly inhibited by riboflavin analogs, such as lumiflavin, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), and to a lesser extent by amiloride.
