Summary: The protein encoded by this gene is a GTPase that localizes to the mitochondrion. The encoded protein binds to the 3' terminal stem loop of 12S mitochondrial rRNA and is required for proper assembly of the 28S small mitochondrial ribosomal subunit. Deletion of this gene has been shown to cause mitochondrial dysfunction, growth retardation, and apoptosis. Several transcript variants encoding different isoforms have been found for this gene.

What's a GeneRIF?

The mitochondrial protein ERAL1 suppresses RNA virus infection by facilitating RIG-I-like receptor signaling.
Title: The mitochondrial protein ERAL1 suppresses RNA virus infection by facilitating RIG-I-like receptor signaling.
Three women from three different families presented with signs of PS, including deafness and ovarian dysgenesis. We employed exome sequencing and identified a homozygous missense mutation in the ERAL1 gene, c.707A > T. The mutation leads to a damaging p.Asn236Ile substitution that is likely to interfere with the GTP binding capacity of the ERAL1 protein.
Title: A homozygous missense mutation in ERAL1, encoding a mitochondrial rRNA chaperone, causes Perrault syndrome.
Data show that loss of ERAL1 leads to rapid decay of nascent 12S mt-rRNA, consistent with a role as a mitochondrial RNA chaperone.
Title: Human ERAL1 is a mitochondrial RNA chaperone involved in the assembly of the 28S small mitochondrial ribosomal subunit.

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.

Status: REVIEWED

Description

Transcript Variant: This variant (4) uses an alternate splice junction at the 3' end of an exon 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).
