ELAC1 recombinant protein is derived from the human ELAC1 gene, which encodes a conserved eukaryotic enzyme belonging to the ELAC (elaC homolog) family. ELAC1 is primarily recognized as a tRNA-processing endoribonuclease involved in the maturation of transfer RNA (tRNA). Specifically, it catalyzes the removal of the 3' trailer sequences from precursor tRNA (pre-tRNA) molecules, a critical step in generating functional tRNAs required for protein synthesis. This enzymatic activity is essential for mitochondrial function, as ELAC1 localizes to mitochondria and processes mitochondrial tRNA, ensuring proper mitochondrial translation and energy production.
Research on ELAC1 has expanded beyond its canonical role, with studies implicating it in broader cellular processes, including genome stability and apoptosis. Mutations or dysregulation of ELAC1 have been linked to human diseases, such as prostate cancer and Hoyeraal-Hreidarsson syndrome, a severe form of dyskeratosis congenita. These associations highlight its potential as a therapeutic target or biomarker.
The recombinant ELAC1 protein is typically produced using heterologous expression systems (e.g., E. coli or mammalian cells) to enable functional and structural studies. Purification methods often employ affinity tags (e.g., His-tag) for high yield and purity. Recombinant ELAC1 facilitates in vitro assays to dissect its enzymatic mechanisms, substrate specificity, and interactions with cofactors. It also serves as a tool for screening inhibitors or modulators in drug discovery. Furthermore, its recombinant form supports investigations into disease-related mutations, aiding in the understanding of molecular pathology and the development of targeted therapies. Overall, ELAC1 recombinant protein is a vital resource for advancing both basic research and translational applications in mitochondrial biology and human diseases.
