tjp2 togel 🎭 New tight junction protein 2 variant causing progressive

tjp2 togel - Conclusions Our iPSCderived in vitro hepatocyte sapporo88 52 system revealed canalicular membrane disruption in TJP2 deficient hepatocytes and demonstrated the ability to model cholestatic disease with TJP2 deficiency to serve as a platform for further pathophysiologic study and drug discovery Lay summary We investigated a genetic liver disease The latest addition to this family of diseases is tight junction protein 2 TJP2 deficiency This protein is also known as zona occludens 2 ZO2 The patients so far presented all have homozygous proteintruncating mutations A complete absence of this protein was demonstrated These children presented with severe liver disease some TJP2 protein expression summary The Human Protein Atlas Genetic testing revealed a novel homozygous TJP2 variant causing PFIC4 TJP2NM0048173c3334CT 3334CT The consanguineous family consists of the father and mother both heterozygous and their 12 children of which five carry the variant in a homozygous state however these five siblings have highly variable expression of PFIC4 Mutations in TJP2 encoding zona occludens 2 and liver Genomewide linkage analysis showed linkage to the DFNA36 606705 locus on chromosome 9q with a maximum lod score of 444 However no pathogenic mutations were identified in the TMC1 gene 606706 Instead a putative asp924toval D924V variant was identified in the TJP2 gene 607709 on chromosome 9q12q13 In silico mRNA and DNA profiles of TJP family members in multiple cancer cell lines By evaluating the mRNA expression of TJP1 TJP2 and TJP3 in 40 different cancer cell lines we found that TJP1 The encoded protein functions as a component of the tight junction barrier in epithelial and endothelial cells and is necessary for proper assembly of tight junctions Mutations in this gene have been identified in patients with hypercholanemia and genomic duplication of a 270 kb region including this gene causes autosomal dominant deafness51 TJP1 TJP2 and TJP3 are closely related scaffolding proteins that link tight junction TJ transmembrane proteins such as claudins junctional adhesion molecules and occludin to the actin cytoskeleton PubMed16129888 The tight junction acts to limit movement of substances through the paracellular space and as a boundary between the TJP2 tight junction protein 2 NIH Genetic Testing Registry TJP3 Gene GeneCards ZO3 Protein ZO3 Antibody Tight junction protein ZO2 Tight junction protein ZO2 is a protein that in humans is encoded by the TJP2 gene 5 Tight junction proteins TJPs belong to a family of membraneassociated guanylate kinase MAGUK homologs that are involved in the organization of epithelial and endothelial intercellular junctions High expression of tight junction protein 1 as a predictive Tight junction protein ZO2 Wikipedia The TJP2 gene was first discovered by Gumbiner et al in 1991 The TJP2 gene is located on chromosome 9q2111 and has a total of 80932 base pairs and includes 23 exons The TJP2 gene product is the tight junction protein 2 also called zona occludens 2 ZO2 which belongs to the membraneassociated guanylate cyclase family By using CRISPRcas9 technology we demonstrated that TJP2 c1202A G was pathogenic at least partially by increasing the expression and nuclear localization of TJP2 apakah wa error protein With the minigene assay we showed that TJP2 c266811A G was a new pathogenic variant by inducing abnormal splicing of TJP2 gene and translation of prematurely ZO2Tjp2 suppresses Yap and Wwtr1Tazmediated Nature TJP2 Gene GeneCards ZO2 Protein ZO2 Antibody Despite the absence of Tjp2 from hepatocytes in both strains 05 CA dietinduced cholestasis in Tjp2icKO HC mice was mild compared to Tjp2cKO animals arguing against overt defects of the canalicular TJ seen in other mouse models with severe disease 1 2 InTjp2cKO liver Cldn1 protein was reduced but the expression and localization of TJP2ZO2inactivating mutations in humans cause progressive cholestatic liver disease Liverspecific deletion of Tjp2 in the mouse Tjp2 cKO mice leads to mild progressive cholestasis without GeneCards Summary for TJP2 Gene TJP2 Tight Junction Protein 2 is a Protein Coding gene Diseases associated with TJP2 include Cholestasis Progressive Familial Intrahepatic 4 and Hypercholanemia Familial 1 Among its related pathways are BloodBrain Barrier and Immune Cell Transmigration VCAM1CD106 Signaling and Signaling by Rho GTPases Abstract To assess the spectrum of pediatric clinical phenotypes in TJP2 disease we reviewed records of our seven patients in whom intrahepatic cholestasis was associated with biallelic TJP2 variants 13 12 novel and correlated clinical manifestations with mutation type The effect of a splicing variant was analyzed with a minigene assay TJP1 TJP2 and TJP3 are closely related scaffolding proteins that link tight junction TJ transmembrane proteins such as claudins junctional adhesion molecules and

familial intrahepatic cholestasis and intrahepatic cholestasis of pregnancy To our knowledge no cases of BRIC caused by a single variant mutation of TJP2 have been reported We describe a 15yearold female presenting with recurrent episodes of jaundice vomiting with intense pruritus anorexia and weight loss Blood work revealed elevated serum conjugated bilirubin TJP2 is a cytosolic component of several classes of cellcell junctions 10 Through interaction with cytoskeletal proteins and integral membrane proteins members of the TJP family are important in the localisation of components of these paracellular structures Human TJP2 generates 2 isoforms A and C both widely expressed 11 Mutations in TJP2 cause progressive cholestatic liver disease Human iPSCderived hepatocyte system models
