Also known as: Dfnb59; Gm1001
Summary: Involved in several processes, including pexophagy; programmed cell death in response to reactive oxygen species; and regulation of peroxisome organization. Acts upstream of or within detection of mechanical stimulus involved in sensory perception of sound and stereocilium maintenance. Located in several cellular components, including cytoskeleton; peroxisomal membrane; and stereocilium base. Used to study autosomal recessive nonsyndromic deafness 59. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 59. Orthologous to human PJVK (pejvakin). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Studied role of pejvakin in preventing noise induced hearing loss by protecting auditory hair cells through mediating pexophagy, which plays a key role in noise-induced peroxisome proliferation; results suggest pejvakin acts as a redox-activated pexophagy receptor.
Title: Pejvakin-mediated pexophagy protects auditory hair cells against noise-induced damage.
Results demonstrate that pejvakin is required to sustain outer hair cell activity and survival in a cell-autonomous manner and imply pejvakin defects in sensory hearing loss rather than auditory neuropathy spectrum disorder; show that pejvakin forms protein complexes with Rho effectors, including ROCK2.
Title: Conditional deletion of pejvakin in adult outer hair cells causes progressive hearing loss in mice.
Study describes a genetic form of noise-induced hearing loss , by showing that pejvakin deficiency in mice and DFNB59 patients leads to hypervulnerability to sound, due to a peroxisomal deficiency.
Title: Hypervulnerability to Sound Exposure through Impaired Adaptive Proliferation of Peroxisomes.
The pejvakin allele described here introduces a premature stop codon, causes outer hair cell defects, and leads to progressive hearing loss.
Title: A forward genetics screen in mice identifies recessive deafness traits and reveals that pejvakin is essential for outer hair cell function.

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.
