Predicted to enable neuropeptide hormone activity. Predicted to be involved in cellular response to starvation and negative regulation of appetite. Predicted to act upstream of or within several processes, including adult feeding behavior; neuropeptide signaling pathway; and positive regulation of MAPK cascade. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in obesity. Orthologous to human CARTPT (CART prepropeptide).
