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 (2; also known as Gbeta5S) differs in the 5' UTR compared to variant 1. This difference causes translation initiation at a downstream AUG and results in an isoform (2) with a shorter N-terminus, compared to isoform 1.

NR_073186.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (3) uses an alternate 5' exon structure and contains an alternate internal exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
