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_001164406.1 → NP_001157878.1 steroid receptor RNA activator 1 isoform b

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate splice site in the 3' coding region, which results in a frameshift, compared to variant 1. It encodes isoform b, which has a shorter and distinct C-terminus, compared to isoform a.

RNA

NR_028355.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (3) contains an alternate segment, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
