Serine/arginine-rich splicing factor 7 (SRSF7), formerly known as SFRS7. is a member of the serine/arginine (SR)-rich protein family involved in constitutive and alternative pre-mRNA splicing. These proteins play critical roles in spliceosome assembly by binding specific exonic or intronic splicing enhancer sequences through their RNA recognition motifs (RRMs), while their RS domains mediate protein-protein interactions essential for splice site selection. SRSF7 is ubiquitously expressed in mammalian cells and regulates the splicing of numerous transcripts linked to cell cycle progression, apoptosis, and DNA repair. It has been implicated in maintaining genome stability and cellular homeostasis, with dysregulation observed in cancers, neurodegenerative disorders, and viral infections.
Recombinant human SRSF7 protein is typically produced using bacterial or eukaryotic expression systems, enabling structural and functional studies. Its recombinant form preserves the modular structure, including the N-terminal RRM for RNA binding and the C-terminal RS domain for interaction with spliceosomal components. Researchers employ recombinant SRSF7 to investigate splicing mechanisms, map protein-RNA interaction networks, and screen small molecules targeting aberrant splicing in diseases. Notably, SRSF7 overexpression correlates with tumor aggressiveness in several cancers, making it a potential therapeutic target. Recent studies also explore its non-canonical roles in mRNA export, translation, and microRNA processing, broadening its significance in post-transcriptional gene regulation.
