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: REVIEWED

    Description
    Transcript Variant: This variant (3) differs in its 5' and 3' ends and uses a downstream start codon, compared to variant 1. The resulting protein (isoform 3) has a shorter N-terminus and a distinct and shorter C-terminus when it is compared to isoform 1.
