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_001272077.2 → NP_001259006.1 GTP-binding protein Rit2 isoform 2

See identical proteins and their annotated locations for NP_001259006.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an alternate internal exon in the 3' coding region which results in a frameshift and an early stop codon, compared to variant 1. The encoded isoform (2) is shorter and has a distinct C-terminus, compared to isoform 1.
