    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_150091.2

      Status: VALIDATED

      Description
      Transcript Variant: This variant (2) differs in the 5' UTR, 3' UTR, and 3' coding region, compared to variant 1. This results in a protein (isoform 2) with a longer, distinct C-terminus, compared to isoform 1. Variants 2 and 3 encode the same protein (isoform 2).
