Description

ELAVL1, also known as HuR, is an RNA-binding protein that plays a central role in post-transcriptional gene regulation by stabilizing mRNA transcripts and modulating their translation. This protein recognizes AU-rich elements in the 3' untranslated regions of target mRNAs, influencing the expression of genes involved in cell proliferation, stress responses, and inflammation. Given its documented involvement in cancer progression and cellular stress pathways, ELAVL1 has become an important target for researchers investigating tumor biology, inflammatory diseases, and RNA metabolism.

This recombinant monoclonal antibody, clone 11D12, offers the consistency and reproducibility that demanding experimental workflows require. Produced using recombinant technology with a defined sequence, it eliminates the lot-to-lot variability often encountered with traditional hybridoma-derived antibodies, ensuring that your results remain comparable across extended studies and collaborative projects.

Validation testing demonstrates robust performance across multiple applications. Western blot analysis detects a clean 36 kDa band matching the predicted molecular weight across a diverse panel of human cell lines, including HEK293, U-251MG, PC-3, HL-60, HepG2, COLO205, HeLa, and Jurkat cells at dilutions between 1:500 and 1:2000. Immunohistochemistry staining has been validated in paraffin-embedded human prostate cancer tissue, while immunofluorescence studies in HeLa cells confirm nuclear localization consistent with ELAVL1's known biology. Flow cytometry analysis in MCF-7 cells further demonstrates the antibody's versatility for quantitative single-cell studies.

Whether investigating RNA-protein interactions, exploring stress granule dynamics, or characterizing ELAVL1 expression patterns in disease models, this antibody provides the flexibility and reliability needed for rigorous research.

Target Background

Function

RNA-binding protein that binds to the 3'-UTR region of mRNAs and increases their stability. Involved in embryonic stem cells (ESCs) differentiation: preferentially binds mRNAs that are not methylated by N6-methyladenosine (m6A), stabilizing them, promoting ESCs differentiation. Binds to poly-U elements and AU-rich elements (AREs) in the 3'-UTR of target mRNAs. Binds avidly to the AU-rich element in FOS and IL3/interleukin-3 mRNAs. In the case of the FOS AU-rich element, binds to a core element of 27 nucleotides that contain AUUUA, AUUUUA, and AUUUUUA motifs. Binds preferentially to the 5'-UUUU[AG]UUU-3' motif in vitro. With ZNF385A, binds the 3'-UTR of p53/TP53 mRNA to control their nuclear export induced by CDKN2A. Hence, may regulate p53/TP53 expression and mediate in part the CDKN2A anti-proliferative activity. May also bind with ZNF385A the CCNB1 mRNA. Increases the stability of the leptin mRNA harboring an AU-rich element (ARE) in its 3' UTR.
