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_001153115.1

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) is lacking two consecutive in-frame coding exons compared to variant 1, resulting in a shorter isoform (2) missing an internal protein segment compared to isoform 1. Variants 2 and 7 both encode the same isoform (2).

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) contains an alternate segment at the 5' end, and an alternate exon at the 3' end (causing a frame-shift) compared to variant 1. This results in translation initiation from a downstream start codon and a shorter isoform (3) with a distinct C-terminus compared to isoform 1.
