Summary
Expression of this gene is induced by estrogen and the encoded protein has been characterized as a transmembrane protein. The encoded protein has been found in to correlate with survival in certain carcinomas (PMID: 21102415) and may be important for cellular response to stress (PMID: 21072319). Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2012]

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 (2) uses an alternate in-frame splice site in the 5' coding region and lacks two alternate in-frame exons in the 5' coding region compared to variant 1. The resulting protein (isoform 2) is shorter compared to isoform 1.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (4) uses an alternate 5' exon structure and thus differs in the 5' UTR and 5' coding region, and also uses an alternate splice site in the 3' coding region, which results in a frameshift, compared to variant 1. These differences cause translation initiation at a downstream start codon and result in an isoform (4) with a shorter N-terminus and distinct C-terminus, compared to isoform 1.
