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_001271532.1 → NP_001258461.1 insulin-induced gene 2 protein isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (4) lacks an exon which contains a portion of the 5' UTR and 5' coding region including the start codon, compared to variant 1. These differences cause translation initiation at a downstream start codon and result in an isoform (2) with a shorter N-terminus, compared to isoform 1.
