Teleost leptins are a family of peptide hormones found in fish (teleostei) that are orthologs of the mammalian hormone leptin. The teleost and mammalian leptins appear to have similar functions, namely, regulation of energy intake and expenditure.
The leptin (LEP) hormone was long thought to be specific to mammals, but in recent years the gene (lep) has been found in amphibia such as the tiger salamander (Ambystoma tigrinum),[2][3] and the African clawed frog (Xenopus laevi).[4] The discovery of lep in puffer fish (Takifugu rubripes)[5] demonstrates the ancient ancestry of this hormone.
