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_001170552.1 → NP_001164023.1 krev interaction trapped protein 1 isoform 2

See identical proteins and their annotated locations for NP_001164023.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) differs in the 5' UTR and lacks an alternate in-frame exon, compared to variant 1, resulting in a shorter protein (isoform 2), compared to isoform 1. Isoform 2 is also known as Krit1B.

Status: VALIDATED

Description

Transcript Variant: This variant (3) has multiple differences, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
