Recombinant human NSUN7 protein is a genetically engineered form of the NSUN7 (NOL1/NOP2/SUN domain-containing protein 7) enzyme, which belongs to the NSUN family of RNA methyltransferases. NSUN7 is primarily involved in post-transcriptional RNA modifications, specifically catalyzing the methylation of cytosine residues in RNA molecules (m5C modification), a process critical for RNA stability, localization, and translation efficiency. While the biological functions of NSUN7 remain less characterized compared to other family members (e.g., NSUN2 or NSUN6), studies suggest its role in spermatogenesis and male fertility, with high expression observed in testes. It may also participate in cellular stress responses and tumorigenesis, though mechanistic details are under investigation.
The recombinant protein is typically produced in heterologous systems like *E. coli* or mammalian cells, enabling large-scale purification for functional and structural studies. Researchers utilize recombinant NSUN7 to dissect its substrate specificity, enzymatic kinetics, and interactions with RNA or protein partners. Its dysregulation has been tentatively linked to reproductive disorders and certain cancers, positioning it as a potential therapeutic target. However, challenges persist in fully mapping its physiological RNA targets and regulatory networks. Advances in CRISPR-based screening and high-throughput sequencing may accelerate the elucidation of NSUN7's roles in health and disease.
