PIP4K2B Protein, Human (Active)
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, Human (Active) is the recombinant human-derived PIP4K2B protein, expressed by E. coli, with N-Avi labeled tag.

Descripciòn
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, Human (Active) is the recombinant human-derived PIP4K2B protein, expressed by E. coli, with N-Avi labeled tag.
Background
PIP4K2B Protein actively participates in the biosynthesis of phosphatidylinositol 4,5-bisphosphate, demonstrating a preference for GTP over ATP in the phosphorylation of PI(5)P, and its enzymatic activity is intricately linked to physiological GTP concentrations. The protein's unique GTP-sensing ability plays a critical role in metabolic adaptation. Notably, PIP4Ks, including PIP4K2B, exert a negative regulatory influence on insulin signaling through a catalytic-independent mechanism. They form interactions with PIP5Ks, effectively suppressing PIP5K-mediated synthesis of PtdIns(4,5)P2 and impeding insulin-dependent conversion to PtdIns(3,4,5)P3. This multifaceted role underscores the importance of PIP4K2B in modulating key signaling pathways that contribute to cellular homeostasis and metabolic responsiveness.
