**Background of PANK1 Recombinant Protein**
Pantothenate kinase 1 (PANK1) is a critical enzyme encoded by the *PANK1* gene, playing a central role in coenzyme A (CoA) biosynthesis. It catalyzes the first regulatory step in the CoA pathway by phosphorylating pantothenate (vitamin B5) to form 4’-phosphopantothenate. CoA is essential for cellular metabolism, including fatty acid synthesis, energy production via the tricarboxylic acid (TCA) cycle, and acetylation reactions. PANK1 exists in two isoforms (PANK1α and PANK1β) generated by alternative splicing, differing in subcellular localization and regulatory mechanisms. Dysregulation of PANK1 has been linked to metabolic disorders, neurodegeneration, and rare genetic conditions like pantothenate kinase-associated neurodegeneration (PKAN).
Recombinant PANK1 protein is produced using biotechnological platforms (e.g., *E. coli* or mammalian expression systems) to enable functional and structural studies. Its purification often involves affinity tags (e.g., His-tag) for high yield and purity. Researchers utilize this protein to investigate enzymatic kinetics, substrate specificity, and interactions with regulatory molecules (e.g., acetyl-CoA feedback inhibition). Additionally, it serves as a tool for drug discovery targeting CoA-related pathologies and for elucidating metabolic adaptations in diseases like cancer or diabetes. The availability of recombinant PANK1 has advanced understanding of CoA biology and its therapeutic potential in metabolic and neurological diseases.
