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 (1) represents the longest transcript and encodes the longer isoform (a).

    See identical proteins and their annotated locations for NP_001278257.1

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) contains alternate 5' exon structure, and it thus differs in its 5' UTR and initiates translation at a downstream in-frame start codon, compared to variant 1. The encoded isoform (b) is shorter at the N-terminus, compared to isoform a.

RNA

  1. NR_111929.2 RNA Sequence

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) contains alternate 5' exon structure and lacks five internal exons, compared to variant 1. This variant is represented as non-coding because it lacks most of the coding region, including the translational start codon, as found in variant 1.
