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.

NM_001098404.1 → NP_001091874.1 nuclear receptor subfamily 1 group I member 2 isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate, in-frame, downstream acceptor splice site at one of the coding exons compared to transcript variant 1, resulting in an isoform (2, also known as PXR.2) that is missing a 41 aa segment compared to isoform 1.
