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 (4) has an alternate 5' terminal exon that includes an upstream in-frame AUG start codon, and lacks an in-frame exon in the 3' coding region, compared to variant 3. The resulting isoform (4) is longer at the N-terminus but lacks an internal segment near the C-terminus compared to isoform 3.
