Recombinant human PUS7L (Pseudouridine Synthase 7 Homolog-Like) protein is a genetically engineered form of the enzyme encoded by the *PUS7L* gene. Belonging to the pseudouridine synthase family, PUS7L facilitates the post-transcriptional modification of RNA by catalyzing the isomerization of uridine to pseudouridine (Ψ), a prevalent RNA modification crucial for RNA stability, structure, and function. Although structurally homologous to PUS7. PUS7L exhibits distinct substrate preferences and cellular roles. Studies suggest it may target specific RNA molecules, including mRNAs and non-coding RNAs, influencing processes like translation efficiency and RNA-protein interactions.
The recombinant protein is typically produced in heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable high-purity yields for functional studies. Research on PUS7L is emerging, with evidence implicating its involvement in neurodevelopment, germ cell biology, and possibly cancer. Its dysregulation has been linked to intellectual disability disorders and male infertility in model systems. However, detailed mechanistic insights into its physiological targets and regulatory pathways remain limited. Recombinant PUS7L serves as a critical tool for unraveling its catalytic mechanisms, RNA interaction networks, and potential therapeutic applications. Further exploration may uncover novel roles in RNA epitranscriptomics and disease biomarkers.
