PTPRK Antibody, Biotin conjugated

1. PTPRK was identified as a direct target of miR-1260b, and PTPRK expression was inversely correlated with miR-1260b in non-small cell lung cancer cell lines and clinical tissues PMID: 29628123
2. Study found a significant association between PTPRK genetic variants and the risk and age at onset of Alzheimer's disease in two independent samples, and provided initial evidence of several genetic variants in PTPRK influencing the risk of cancer and cholesterol levels. PMID: 28987514
3. The present study identified RSPO fusion transcripts, including three novel transcripts, in one-third of colorectal Traditional serrated adenoma (TSA) and showed that PTPRK-RSPO3 fusions were the predominant cause of RSPO overexpression in colorectal TSA. PMID: 28543708
4. PTPRK plays dual roles in coordinating angiogenesis. It plays a positive role in cell proliferation, adhesion and tubule formation, but suppresses cell migration, in particular, the FGF-promoted migration. PMID: 28259897
5. PTPRK-RSPO3 fusions and RNF43 mutations were found to be characteristic genetic features of traditional serrated adenomas (TSAs). PMID: 26924569
6. By regulating phosphorylation of SRC, RPTPkappa promotes the pathogenic action of rheumatoid arthritis fibroblast-like synoviocytes, mediating cross-activation of growth factor and inflammatory cytokine signalling by TGFbeta in RA FLS. PMID: 25378349
7. Notch and TGF-beta act in concert to stimulate induction of PTPRK, which suppresses EGFR activation in human keratinocytes. PMID: 25609089
8. Findings strongly indicate that the tyrosine phosphorylation of CD133, which is dephosphorylated by PTPRK, regulates AKT signaling and has a critical role in colon cancer progression. PMID: 24882578
9. PTPRK underexpression leads to STAT3 activation and contributes to nasal NK/T-cell lymphoma pathogenesis PMID: 25612622
10. PTPRK showed lower mRNA expression in duodenal mucose of celiac disease patients. PMID: 23820479
11. High expression of PTPRK is associated with prostate cancer. PMID: 24002526
12. Tumor derived mutations of protein tyrosine phosphatase receptor type k affect its function and alter sensitivity to chemotherapeutics in glioma. PMID: 23696788
13. PTPRK is a negative regulator of adhesion, invasion, migration, and proliferation of breast cancer cells. PMID: 23552869
14. PTPkappa was scissored by the processed form of proprotein convertase 5, and galectin-3 binding protein which is over-produced in colon cancer cells and tissues. PMID: 21094132
15. These data describe a novel mechanism of cross-talk between EGFR and TGF-beta pathways, in which RPTP-kappa functions to integrate growth-promoting and growth-inhibiting signaling pathways. PMID: 19864455
16. Our results suggest that GnT-V could decrease human hepatoma SMMC-7721 cell adhesion and promote cell proliferation partially through RPTPkappa. PMID: 19911372
17. RPTP-kappa is a key regulator of EGFR tyrosine phosphorylation and function in human keratinocytes PMID: 16263724
18. the crystal structure of catalytically active, monomeric D1 domain of RPTPkappa at 1.9 A. RPTPkappa is monomeric in solution and crystal structure. PMID: 16672235
19. EGF receptor is activated in human keratinocytes by oxidative inhibition of receptor-type protein-tyrosine phosphatase kappa by ultraviolet irradiation PMID: 16849327
20. EBNA1 apparently disables TGF-beta signaling, which subsequently decreases transcription of the PTPRK tumor suppressor PMID: 17720884
21. PTPRK influences transactivating activity of beta-catenin in non-tumoral and neoplastic cells by regulating the balance between signaling and adhesive beta-catenin, thus providing biochemical basis for the hypothesis of PTPRK as a tumor suppressor gene. PMID: 18276111
22. overexpression of GnT-V in a hepatoma cell line not only induced the addition of beta1,6 GlcNAc branch to N-glycan of RPTPkappa but also decreased the protein level of RPTPkappa PMID: 19236842
23. These data indicate that PPTRK positively regulates ERK1/2 phosphorylation, which impacts CD4(+) T cell development. PMID: 19800317
