    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.

      See identical proteins and their annotated locations for NP_001291879.1

      Status: REVIEWED

      Description
      Transcript Variant: This variant (MOR-1D) differs in the 3' UTR and has multiple coding region differences, compared to variant MOR-1U, one of which results in a frameshift. The resulting protein (isoform MOR-1D) has a distinct C-terminus and is shorter than isoform MOR-1U.
