PIP4K2B protein actively synthesizes phosphatidylinositol 4,5-bisphosphate and preferentially selects GTP over ATP in PI (5) P phosphorylation. The enzyme activity is related to physiological GTP levels. Its unique GTP-sensing ability is critical for metabolic adaptation. PIP4K2B Protein, Human (His) is the recombinant human-derived PIP4K2B protein, expressed by E. coli , with N-10*His labeled tag.
