Satiety factor closely associated with the actions of leptin and neuropeptide Y; this anorectic peptide inhibits both normal and starvation-induced feeding and completely blocks the feeding response induced by neuropeptide Y and regulated by leptin in the hypothalamus. It promotes neuronal development and survival in vitro. . This is the function of Ensembl gene identifier ENSG00000164326 (CARTPT, CART prepropeptide).
