PTPRQ protein tyrosine phosphatase receptor type Q [Homo sapiens (human)] - Gene

Summary

Official Symbol: PTPRQprovided by HGNC
Official Full Name: protein tyrosine phosphatase receptor type Qprovided by HGNC
Primary source: HGNC:HGNC:9679
See related: Ensembl:ENSG00000139304 MIM:603317; AllianceGenome:HGNC:9679
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: DFNA73; DFNB84; DFNB84A; PTPGMC1; R-PTP-Q
Summary: This locus encodes a member of the type III receptor-like protein-tyrosine phosphatase family. The encoded protein catalyzes the dephosphorylation of phosphotyrosine and phosphatidylinositol and plays roles in cellular proliferation and differentiation. Mutations at this locus have been linked to autosomal recessive deafness. [provided by RefSeq, Mar 2014]
Expression: Biased expression in fat (RPKM 1.2), lung (RPKM 1.0) and 9 other tissues See more

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.
