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.

mRNA and Protein(s)

NM_001307936.2 → NP_001294865.1 sodium-coupled neutral amino acid symporter 2 isoform 2

See identical proteins and their annotated locations for NP_001294865.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks an exon in its 5' coding region compared to variant 1. This variant represents translation initiation at an alternate start codon compared to variant 1; the 5'-most initiation codon, as used in variant 1, is associated with a truncated ORF that would render the transcript a candidate for nonsense-mediated decay (NMD). Leaky scanning may allow translation initiation at the alternate start codon to encode an isoform (2) that has a distinct and shorter N-terminus, compared to isoform 1.
