    Summary
    This gene encodes a protein that contains multiple simple repeats. The encoded protein binds RNA and promotes pre-mRNA splicing, particularly of transcripts with poor splice sites. The protein also recognizes a specific DNA sequence found in the human hepatitis B virus (HBV) and represses HBV core promoter activity. There is a pseudogene for this gene on chromosome 1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 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.

    1. NR_103797.2 RNA Sequence

      Status: REVIEWED

      Description
      Transcript Variant: This variant (c) contains an alternate internal exon and uses an alternate splice site at the 3' exon, compared to variant f. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant f, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
