CART Protein, a satiety factor, intricately regulates feeding in connection with leptin and neuropeptide Y. It effectively suppresses regular and starvation-triggered feeding, robustly inhibiting neuropeptide Y-initiated feeding within the hypothalamus. Additionally, CART protein plays a pivotal role in fostering neuronal development and survival in vitro, extending beyond its appetite regulation function. CART Protein, Human (HEK293) is the recombinant human-derived CART protein, expressed by HEK293 , with tag free.
