I'm doing an anatomy project and need to know what meletonin targets to help induce the circadian cycle.

Melatonin is a hormone produced by the pituitary gland by the way.

As Far as a Particular Cell is Concerned, I don't Know, they Would Have to Be MT(1-4)+. The Location, the SCN of the Hypothalamus, See Rozerem. Additionally, the Pineal Gland (Negative Feedback).

Melatonin receptors are expressed throughout the body. However, it is melatonin receptors in the brain that are related to the circadian cycle. The prime candidate for the location of melatonins effect on circadian rhythms is the superchiasmatic nucleus, as show by the following paper:
Liu C, Weaver DR, Jin X, Shearman LP, Pieschl RL, Gribkoff VK & Reppert SM (1997) Molecular dissection of two distinct actions of melatonin on the suprachiasmatic circadian clock. Neuron 19, 91–102.

melatonin is produced by the pineal gland in the brain, by the conversion of tryptophan, it is only produced at night and i immagine that the lymphatic system distributes hormones through out the body so lymph nodes and blood, are a good place to start, menatonin is also a monoamine same epinephrine and there is a relationship between menatonin an sleep disorders this is also regulated in part by the cardiac cycle.
