    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_001164040.1

      Status: VALIDATED

      Description
      Transcript Variant: This variant (2) uses an alternate splice junction at the 3' end of the first exon, which causes a frameshift and use of a downstream AUG. The resulting isoform (2) is shorter at the N-terminus compared to isoform 1.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (3) lacks an alternate in-frame exon compared to variant 1. The resulting isoform (3) has the same N- and C-termini but is shorter compared to isoform 1.
