Summary: This gene encodes a multi-pass membrane protein that is a member of a family of sodium and chloride-ion dependent transporters. The encoded protein transports taurine and beta-alanine. There is a pseudogene for this gene on chromosome 21. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

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.

Status: REVIEWED

Description

Transcript Variant: This variant (4) lacks an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the translational start codon used in variant 1 renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
