| description | The cocaine and amphetamine regulated transcript (CART) is a brain-localised peptide that acts as a satiety factor in appetite regulation. CART was found to inhibit both normal and starvation-induced feeding, and completely blocks the feeding response induced by neuropeptide Y. CART is regulated by leptin in the hypothalamus, and can be transcriptionally induced after cocaine or amphetamine administration []. CART has also been suggested to activate ERK1 through interaction with a specific G-protein coupled receptor []. Posttranslational processing of CART produces an N-terminal CART peptide and a C-terminal CART peptide. The C-terminal CART peptide has been isolated from the hypothalamus, nucleus accumbens, and the anterior pituitary lobe in rats. C-terminal CART is the biologically active part of the molecule affecting food intake. The structure of C-terminal CART consists of a disulphide-bound fold containing a β-hairpin and two adjacent disulphide bridges []. |
