Serum response factor (SRF) mRNA 3' untranslated region (SRF mRNA 3'UTR)

The Serum response factor (SRF) mRNA 3' untranslated region (3'UTR) is a critical regulatory segment of the SRF transcript that governs the stability and translation of the SRF protein (UniProt P11831). SRF is a master transcription factor essential for the expression of genes involved in the cytoskeleton, muscle differentiation, and cell proliferation (PubMed: 16415855). The 3'UTR contains conserved binding sites for several microRNAs, most notably miR-1 and miR-133, which are pivotal in cardiac and skeletal muscle development and function (PubMed: 17496892). Dysregulation of the SRF mRNA 3'UTR-microRNA axis is implicated in various pathologies, including cardiac hypertrophy, heart failure, and certain cancers where SRF-mediated gene expression is aberrant (PubMed: 24631211). Therapeutic strategies targeting this region typically involve the use of microRNA mimics or antisense oligonucleotides to either suppress or enhance SRF expression depending on the disease context. Because SRF is vital for normal physiological function, precise targeting is required to avoid adverse effects on healthy muscle tissue and cardiac output. Experimental approaches have demonstrated that modulating this region can influence the progression of cardiac remodeling and fibrosis. Current research focuses on optimizing delivery systems to ensure tissue-specific modulation of the SRF 3'UTR.
