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_001275962.1

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) has an alternate splice site in the 5' region, which results in translation initiation at a downstream AUG codon, compared to variant 1. The resulting isoform (2) has a shorter N-terminus, compared to isoform 1. Both variants 2 and 3 encode the same isoform 2.
