Recombinant human FASTKD1 protein is a genetically engineered version of the endogenous FAST Kinase Domain-containing protein 1. which plays a critical role in mitochondrial RNA metabolism and energy homeostasis. FASTKD1. a member of the FASTK family, is localized to the inner mitochondrial membrane and regulates the stability, processing, and translation of mitochondrial mRNAs. It interacts with mitochondrial ribosomes and modulates the expression of oxidative phosphorylation (OXPHOS) complex subunits, impacting cellular energy production. Dysregulation of FASTKD1 has been linked to mitochondrial disorders, neurodegenerative diseases, and cancer, highlighting its importance in cellular stress responses and apoptosis.
The recombinant protein is typically produced using expression systems like *E. coli* or mammalian cell lines, ensuring post-translational modifications mimic native functionality. Its N-terminal contains a RNA-binding domain and a FASTK-like domain, critical for RNA interactions. Researchers employ recombinant FASTKD1 to study mitochondrial gene regulation mechanisms, screen for modulators of OXPHOS activity, and explore therapeutic strategies for mitochondrial dysfunction-related conditions. It also serves as a tool to investigate crosstalk between mitochondrial RNA processing and metabolic signaling pathways. The availability of recombinant FASTKD1 facilitates structural studies, antibody development, and disease modeling, advancing our understanding of mitochondrial biology in health and disease.
