HuR/ELAVL1 is an RNA-binding protein involved in differentiation and stress response that acts primarily by stabilizing messenger RNA (mRNA) targets. HuR comprises three RNA recognition motifs (RRMs) where the structure and RNA binding of RRM3 and of full-length HuR remain poorly understood.

While many RNA‐binding proteins have been shown to bind to AREs in vitro, neither the functional consequences nor the physiological significance of their interactions are known. Here we demonstrate a role for the embryonic lethal abnormal visual (ELAV) RNA‐binding protein HuR in mRNA turnover in vivo. Background: The RNA-binding protein HuR is involved in a range of cellular processes and several diseases.Results: We reveal the characteristics of HuR binding using genomic methods and explore its network of targets.Conclusion: Our results reveal the complexity of RBP binding, corroborate the concept of post-transcriptional networks and suggest an interplay between miRNAs and RBPs Human antigen R (HuR) is an RNA binding protein that binds to the AU-rich element (ARE) of specific mRNA and is involved in the export and stabilization of ARE-mRNA. Our recent report unveiled that the E4orf6 gene deleted oncolytic adenovirus (dl355) replicated for certain types of cancers where ARE-mRNA is stabilized. The human embryonic lethal abnormal vision-like protein, HuR, is a member of the Hu family of RNA-binding proteins. Over the past decade, this ubiquitously expressed protein has been extensively investigated in cancer research because it is involved in the regulation of mRNA stability and translation in many cell types. RNA-binding proteins (RBPs) are key players in post-transcriptional events.

Lemay et al recently reported that the RNA binding protein HuR directly interacts with the ribonuclease H (RNase H) domain of HIV-1 reverse transcriptase (RT) and influences the efficiency of viral reverse transcription (Lemay et al., 2008, Retrovirology 5:47). HuR is a member of the embryonic lethal abnormal vision protein family and contains 3 RNA recognition motifs (RRMs) that bind AU-rich elements (AREs). What Is New? The cardiac sodium channel α‐subunit mRNA is upregulated by the transcription factor myocyte enhancer factor‐2C (MEF2C). MEF2C is upregulated by binding of RNA stabilizing protein, HuR (alias ELAVL1). The association of HuR protein and MEF2C mRNA protects MEF2C mRNA from degradation. Human antigen R (HuR) is a member of the Hu family of RNA-binding proteins. This molecule, which was first described in tumors nearly two decades ago, has recently received much attention in tumor-related research because it regulates the expression of many tumor-associated molecules through posttranscriptional regulatory mechanisms, thereby affecting biological characteristics.

The RNA-binding protein (RBP) Hu-antigen R (HuR) is a central player in posttranscriptional regulation of cancer-related gene expression, and contributes to tumorigenesis, tumor growth, metastasis, and drug resistance.

In ovarian cancer, cytoplasmic accumulation of mRNA-binding protein HuR (ELAVL1) is associated with poor prognosis. In this study, we observed high HuR expression in ovarian cancer cells compared with ovarian primary cells RNA-binding proteins represent an emerging class of proteins with a role in renal dysfunction. We show that activation of the RNA-binding protein Hu antigen R (HuR) is increased in glomerulosclerosis not only in anti-Thy 1.1 nephritis model but also in varied human glomerular diseases.

Branchpoint binding protein binder in till Branchpoint samt U2AF hjälpprotein -Stänger transkription oavsett hur många aktivatorer det finns. RNA pol 1. The RNA-binding protein, HuR, associates with the HuR mRNA, but the consequences of this interaction are unknown.

The RNA-binding protein HuR associates with the p53 mRNA, as reported previously, and with the NPM mRNA, computationally predicted to be a target of HuR. Here, we show that HuR binds the NPM and p53 3′-untranslated regions and stabilizes these mRNAs in polyamine-depleted intestinal epithelial cells. Albeit the suppression of mRNA translation may derive from eIF3a binding to the 5′-UTRs of target mRNAs, how eIF3a may accelerate mRNA translation remains unknown. In this study, we show that eIF3a up-regulates translation of Chk1 but not Chk2 mRNA by interacting with HuR, which binds directly to the 3′-UTR of Chk1 mRNA. 2018-12-08 · Human antigen R (HuR) functions as a major post-transcriptional regulator of gene expression through its RNA-binding activity. HuR is composed by three RNA recognition motifs, namely RRM1, RRM2, and RRM3.

Several RBPs have been reported as The RNA-binding protein HuR binds to elements rich in adenylate and uridylate (AU-rich elements) in target mRNAs and stabilizes them against degradation. The complete spectrum of genes whose expression is regulated by HuR and are the basis for the broad range of cellular functions of the protein is incompletely understood. Human antigen R (HuR) is an RNA-binding protein that regulates the stability, translation, and nucleus-to-cytoplasm shuttling of its target mRNAs.

PDCD4 mRNA translation is regulated by an interplay between the oncogenic microRNA miR-21 and the RNA-binding protein (RBP) HuR in response to LPS stimulation, but the role of other regulatory factors remain unknown.

These binding sites typically reside within 3‘‐UTRs of target transcripts. 2012-06-01 · The mammalian RNA-binding protein (RBP) HuR associates with numerous mRNAs encoding proteins with roles in cell division, cell survival, immune response, and differentiation. HuR was known to stabilize many of these mRNAs and/or modulated their translation, but the molecular processes by which HuR affected the fate of target mRNAs was largely unknown. The mammalian RNA-binding protein (RBP) HuR associates with numerous mRNAs encoding proteins with roles in cell division, cell survival, immune response, and differentiation.

Although primarily known for binding to the 3′ UTRs of mRNAs and increasing their intrinsic stability, several recent reports identified HuR as a bona fide translational regulator as well.
