HuR also known as ELAVL1 is a member of the ELAVL family of RNA-binding proteins that contain several RNA recognition motifs, and selectively bind AU-rich elements (AREs) found in the 3' untranslated regions of mRNAs. plays a crucial role in post-transcriptional regulation of gene expression by binding to AU-rich elements in the 3′-untranslated region of target mRNAs. This interaction stabilizes mRNA transcripts that would otherwise be rapidly degraded, thereby influencing the expression levels of genes involved in critical cellular processes such as growth, differentiation, and response to stress. HuR protein is ubiquitously expressed and is often overexpressed in various tumors, highlighting importance in cancer biology.
