A 2007 study by Iwaniec and Baghossian suggested that treating mice with this protein corrected skeletal abnormalities, and it was found to be upregulated in fetal lung fibroblasts by parathyroid hormone related protein.  It stimulates synthesis of UCP and activates cells expressing melanocyte stimulating hormone, but it down regulates the endo-cannabinoids. It may play a role in fertility, and it binds in the ventromedia

It stimulates synthesis of UCP and activates cells expressing melanocyte stimulating hormone, but it down regulates the endo-cannabinoids. It may play a role in fertility, and it binds in the ventromedial nucleus of the hypothalamus, where it inhibits cells containing agouti-related protein and neuropeptide Y. Counteracted by ghrelin, it is produced by the OB gene in adipocytes, or fat cells, and may be insufficient in some very obese people. FTP, name this hormone that signals satiety, or fullness.
