Also known as: R-PTP-Q
Summary: Predicted to enable protein tyrosine phosphatase activity. Acts upstream of or within several processes, including detection of mechanical stimulus involved in sensory perception of sound; neuromuscular process controlling balance; and vestibular receptor cell morphogenesis. Located in apical plasma membrane and stereocilium base. Is expressed in cochlea; crista ampullaris; inner ear vestibular component; macula of utricle; and saccule. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 73 and autosomal recessive nonsyndromic deafness 84A. Orthologous to human PTPRQ (protein tyrosine phosphatase receptor type Q). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

The reduction in Ptprq observed in miR-96 mutantdiminuendo mice appears to be a major contributor to the morphological, transcriptional and electrophysiological phenotype
Title: A reduction in Ptprq associated with specific features of the deafness phenotype of the miR-96 mutant mouse diminuendo.
The results reveal a distinct phenotype in the vestibular system of Ptprq(-/-) mice and suggest similar hair bundle defects may underlie the vestibular dysfunction reported in humans with mutations in PTPRQ.
Title: Hair bundle defects and loss of function in the vestibular end organs of mice lacking the receptor-like inositol lipid phosphatase PTPRQ.
Three distinct, developmentally regulated isoforms of Ptprq may therefore be expressed on hair bundles of the chick inner ear
Title: Evidence for multiple, developmentally regulated isoforms of Ptprq on hair cells of the inner ear.
Results suggest that PTPRQ and myosin VI form a complex that dynamically maintains the organization of the cell surface coat at the stereocilia base and helps maintain the structure of the overall stereocilia bundle.
Title: Dynamic compartmentalization of protein tyrosine phosphatase receptor Q at the proximal end of stereocilia: implication of myosin VI-based transport.
Ptprq is required for formation of the shaft connectors of the hair bundle, the normal maturation of cochlear hair bundles, and the long-term survival of high-frequency auditory hair cells
Title: A receptor-like inositol lipid phosphatase is required for the maturation of developing cochlear hair bundles.

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.
