CART (cocaine and amphetamine regulated transcript) is a novel, brain-enriched mRNA
which predicts a novel protein without homology to any known protein or peptide. In situ
hybridization studies have identified many expression sites in the brain and periphery as
well as clarify its expression in three known areas. CART mRNA has been localized to
ganglion cells of the retina, lamina X of the spinal cord, mitral and tufted cells of the olfactory
bulb, barrel field neurons of the somatosensory cortex, the anterior pituitary, and the medulla …
