These peptides may have low toxicity to eukaryotic cells and low antimicrobial activities against bacterial and fungi. It is unknown whether these CART-related peptides affect feeding, as mammalian CART peptides do. Expressed by the venom gland. Two short synthetic peptides Tn CRT2 (AA 78-90) and Tn CRT3 (RKGSQMGKKCECP) have antimicrobial activities against both Gram-positive and -negative bacteria, as well against the yeast C.albicans. Belongs to the CART family.
