Why did I have to be Biology retarded.

Okay I have to research the protein Melatonin, and ho hum, it is a drug, too. Thus, finding out information about the protein is proving to be quite fruitless. So, if someone could point me in the right searching direction to figure out in what part of the cell it's made, which cells use it, and what part of the cell uses it, I would appreciate it so much.

melatonin is made in the brain

it controls how sleepy people are by either producing more or less

some people have disorders which means they produce melatonin late and in these people it remains in excess and so they always feel sleepy
