    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: VALIDATED

      Description
      Transcript Variant: This variant (2) differs in the 5' UTR and uses an alternate splice site in the coding region, which results in a frameshift, compared to variant 1. Variants 2, 3, 4 and 5 encode the same small ORF (sORF)-encoded polypeptide (SEP) (isoform 2, also known as MRI-2), which is shorter and has a distinct C-terminus, compared to isoform 1.
