RIPOR2-mediated autophagy dysfunction is critical for aminoglycoside-induced hearing loss.
Title: RIPOR2-mediated autophagy dysfunction is critical for aminoglycoside-induced hearing loss.
The FAM65B is a downstream target of Pink1 and Pink1 phosphorylates FAM65B at serine 46. Phosphorylated FAM65B inhibits autophagy and cell death in the heart.
Title: The circular RNA ACR attenuates myocardial ischemia/reperfusion injury by suppressing autophagy via modulation of the Pink1/ FAM65B pathway.
dysferlin deficiency seems to significantly alter the gene expression of Fam65b and Hdac6 during regeneration, since higher levels of expression of both genes were observed in dysferlin-deficient mice.
Title: Faster regeneration associated to high expression of Fam65b and Hdac6 in dysferlin-deficient mouse.
We propose that Ripor2 deficiency influences abundance and/or post-translational modifications of proteins expressed in both stereocilia and kinocilia. This effect may have a negative impact on the structure and function of the auditory hair cell bundle.
Title: Ripor2 is involved in auditory hair cell stereociliary bundle structure and orientation.
results show that Fam65b expression and phosphorylation can finely tune the amount of active RhoA in order to favor optimal T lymphocyte motility.

RhoC co-localizes with Fam65b in stereocilia and regulates Fam65b oligomerization what is critical for 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.
