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_001359835.2 → NP_001346764.1 iron-sulfur cluster co-chaperone protein HscB isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses and alternate splice site and lacks an alternate coding exon compared to variant 1, that causes a frameshift. The resulting isoform (2) has a shorter and distinct C-terminus compared to isoform 1.

NR_153348.2 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (3) uses an alternate splice junction compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
