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_001025648.2 → NP_001020819.1 SNARE-associated protein Snapin isoform 2

See identical proteins and their annotated locations for NP_001020819.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an additional segment in the 5' region and initiates translation at a downstream start codon compared to variant 1. These differences produce a unique 5' UTR and a protein (isoform 2) with a shorter and distinct N-terminus, compared to isoform 1.
