Mitochondrially encoded tRNA leucine 2 (CUN) also known as MT-TL2 is a transfer RNA which in humans is encoded by the mitochondrial MT-TL2 gene.MT-TL2 is a small 71 nucleotide RNA (human mitochondrial map position 12266-12336) that transfers the amino acid leucine to a growing polypeptide chain at the ribosome site of protein synthesis during translation.
