AMPK gamma 1 is the AMP/ATP-binding subunit of AMP-activated protein kinase (AMPK) and is an important regulator of cellular energy metabolism. It is activated by low ATP levels, enhancing energy production while inhibiting biosynthetic processes and cell growth. AMPK (gamma 1/beta 1/alpha 2) Protein, Human (Unactive, sf9, His) is the recombinant human-derived AMPK (gamma 1/beta 1/alpha 2), expressed by Sf9 insect cells, with His labeled tag.
