Recombinant Human KCNJ2 Protein (HEK293)，His & Flag

KCNJ2, a member of the inward rectifier potassium channel family, plays a crucial role in maintaining cardiac and neuronal excitability by regulating potassium ion flow across cell membranes. Mutations in the KCNJ2 gene have been associated with various genetic disorders, most notably Andersen-Tawil syndrome, characterized by cardiac arrhythmias, periodic paralysis, and dysmorphic features. The study of KCNJ2 recombinant proteins has emerged as a vital avenue for understanding the structure-function relationships of this ion channel and for elucidating the pathophysiological mechanisms underlying KCNJ2-related diseases. By producing and characterizing recombinant KCNJ2 protein, researchers aim to investigate its biophysical properties, ion conductance, and the effects of specific mutations on its function. Such studies not only enhance our comprehension of KCNJ2's role in cellular physiology but also facilitate the development of targeted therapeutic strategies for conditions linked to KCNJ2 dysfunction. Advances in techniques such as X-ray crystallography and cryo-electron microscopy have further propelled this research area, providing insights into the ion channel's architecture and opening new avenues for drug discovery. Overall, the investigation of KCNJ2 recombinant proteins represents a critical intersection of molecular biology, genetics, and medicine, highlighting the importance of ion channels in health and disease.
