Cocaine- and Amphetamine Related Transcript (CART) was initially identified using PCR differential display as mRNA whose levels in the brain was specifically induced by psychomotor stimulants such as cocaine and amphetamine.
CART encodes a secretory single chain polypeptide of 129aa or 116aa protein due to the usage of alternate splicing and processing.
The first 27aa represents the hydrophobic core indicative of signal peptide.
The CART protein also has several basic amino acids near the 54-66 residues with a potential to form multiple proteolytic forms.
CART mRNA was specially enriched in the hypothalamus.
In the striatum, CART expression was induced 4-5 fold by cocaine and amphetamine.
CART is highly conserved between human and mouse (95% amino acid homology); CART gene was localized to human chromosome Most recently, CART has been found to control satiety modulating the actions of two key regulators of food intake, leptin and NPY.
Starvation decreases CART levels in the arcuate nucleus.
Obese animals have virtually no CART.
Peripheral administration of leptin in obese animals induces CART.
Intracereberoventricular injection of recombinant CART inhibits both normal and starvation-induce feeding, and completely inhibits NPY-induce feeding.
Immunoneutralization of CART by administration of anti-CART resulted into higher food intake suggesting that CART is an endogenous regulator of food intake.
CART 55-102 (numbers corresponds to the predicted signal-peptide-cleavage site in the long form of CART) was physiologically active in inhibiting feeding in normal rats.
