Summary: Enables Wnt-protein binding activity; protein homodimerization activity; and protein tyrosine phosphatase activity. Involved in several processes, including negative regulation of canonical Wnt signaling pathway; peptidyl-tyrosine dephosphorylation involved in inactivation of protein kinase activity; and plasma membrane bounded cell projection organization. Located in apical plasma membrane; dendritic spine; and lateral plasma membrane. Is active in GABA-ergic synapse; glutamatergic synapse; and postsynaptic density membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; immune system; and spinal cord. Human ortholog(s) of this gene implicated in nephrotic syndrome type 6. Orthologous to human PTPRO (protein tyrosine phosphatase receptor type O). [provided by Alliance of Genome Resources, Dec 2024]

Data suggest that tyrosine (Tyr399) in PTPRQ Phosphatase (PTPROt) might participate in regulating the activity of this phosphatase toward src Kinases (Src).

Title: Identification of Protein Tyrosine Phosphatase Receptor Type O (PTPRO) as a Synaptic Adhesion Molecule that Promotes Synapse Formation.
PTPROt thus functions as an obligate haploinsufficient TS in CLL, where its expression levels determine its role as a promoter or inhibitor of the tumorigenic process in mice. Partial loss of PTPROt generates the strongest disease phenotype, suggesting that its intermediate expression levels in CLL are selected for.

TLR4 and NF-kappaB/p65 phosphorylation was significantly enhanced in PTPRO over-expressing cells, while significantly down-regulated in PTPRO knockout cells. PTPRO plays ital roles in atherosclerosis (AS) via promoting ox-LDL induced oxidative stress and cell apoptosis through TLR4/NF-kappaB pathway.

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.
