**Background of Recombinant Human PSARL Protein**
Recombinant human PSARL (Proline Synthesis-Associated RNA L protein), also referred to as mitochondrial ribosomal protein L36 (MRPL36), is a protein encoded by the *MRPL36* gene in humans. It plays a crucial role in mitochondrial ribosome assembly and protein synthesis, essential for mitochondrial function and energy production. PSARL is synthesized as a precursor protein, subsequently imported into mitochondria, where it integrates into the large ribosomal subunit to support translation of mitochondrial DNA-encoded proteins involved in oxidative phosphorylation.
Dysregulation of PSARL has been linked to mitochondrial disorders, metabolic syndromes, and cancers, given its impact on cellular energy metabolism and apoptosis. The recombinant form is typically produced using *E. coli* or mammalian expression systems, enabling studies on its structural and functional properties. Engineered variants often include affinity tags (e.g., His-tag) for purification and detection.
Research on recombinant PSARL focuses on elucidating its role in mitochondrial dynamics, stress responses, and interactions with other ribosomal proteins or regulatory RNAs. Its applications span *in vitro* mechanistic studies, drug screening for mitochondrial diseases, and exploring therapeutic strategies targeting energy metabolism pathways in oncology and neurodegeneration. The protein’s conservation across species also facilitates comparative studies in model organisms.
