PKP3 Antibody

1. PKP3 overexpression increases the stability of other desmosomal proteins independently of the increase in DSC2 levels and regulates desmosome formation and stability by a multimodal mechanism affecting transcription, protein stability and cell border localization of desmosomal proteins. PMID: 29146182
2. Children with low 25-hydroxyvitamin D and TMEM16J rs7111432-AA or PKP3 rs10902158-GG polymorphisms were at increased risk for tuberculosis or death. PMID: 26872154
3. Data suggest juxtamembrane regions/domains of desmocollin-2 (DSC2), plakophilin 2 (PKP2), and plakophilin 3 (PKP3) are involved in desmosome formation in epithelial cells; DSC2 participates in desmosome formation in absence of desmoglein 2 (DSG2). PMID: 25972099
4. The results suggest that MMP7 over-expression may be one of the mechanisms by which PKP3 loss leads to increased cell invasion and tumor formation. PMID: 25875355
5. reactive oxygen species (ROS) trigger the c-Src kinase-mediated tyrosine (Tyr)-195 phosphorylation of PKP3. PMID: 25501895
6. These findings reveal Pkp3 as a coordinator of desmosome and adherens junction assembly and maturation through its functional association with Rap1. PMID: 25208567
7. cytoplasmic PKP1/3 are components of mRNA ribonucleoprotein particles and act as posttranscriptional regulators of gene expression. PMID: 25225333
8. Pemphigus vulgaris autoimmune globulin induces Src-dependent tyrosine-phosphorylation of PKP3 and its detachment from DSG3. PMID: 24328683
9. The study describes a new protein variant of the human PKP3 gene, namely PKP3b, which differs from the published PKP3a only at the amino-terminus by the splicing in of the newly identified exon 1b. PMID: 24178805
10. stratifin plays a role in regulating plakophilin-3 incorporation into the desmosomal plaque by forming a plakophilin-3 stratifin complex in the cytosol and thereby affecting desmosome dynamics in squamous epithelial cells. PMID: 24124604
11. In breast cancer, compared with normal tissue, PKP1 and PKP2 expressions were indifferent (P > 0.05), but PKP3 expression was significantly increased PMID: 21947748
12. Plakophilin3 loss leads to an increase in PRL3 levels promoting K8 dephosphorylation, which is required for transformation and metastasis. PMID: 22701666
13. These results demonstrate a strong association of single-nucleotide polymorphisms in the PKP3-SIGIRR-TMEM16J gene region and tuberculosis in discovery and validation cohorts. PMID: 22223854
14. plakoglobin and E-cadherin recruit plakophilin3 to the cell border to initiate desmosome formation PMID: 20859650
15. loss of PKP3 expression during gastric adenocarcinoma progression may indicate an invasive phenotype. PMID: 21194493
16. both loss of PKP1 and up-regulation of PKP3 expression are biologically important events in prostate cancer and are associated with a more aggressive phenotype PMID: 20348237
17. PKP3 mRNA can be used as a marker of subclinical disease in gastrointestinal cancer and thus holds potential clinical relevance as a predictor for disease outcome PMID: 20501752
18. PKP3, whose desmosomal expression and protein interactions are broader than those of PKP1 and -2, is a unique multiprotein binding element in many epithelial desmosomes. PMID: 12707304
19. Cytoplasmic PKP3 is constitutively associated with RNA-binding proteins and indicate an involvement in processes of translation and RNA metabolism. PMID: 16407409
20. The transcriptional repression of PKP3 by ZEB1 contributes to ZEB1-mediated disintegration of intercellular adhesion and epithelial to mesenchymal transition. PMID: 17391671
21. plakophilin3 loss leads to a decrease in cell-cell adhesion leading to the stimulation of neoplastic progression and metastasis PMID: 18729189
