What is "mt-ti"

Mitochondrially encoded tRNA isoleucine also known as MT-TI is a transfer RNA which in humans is encoded by the mitochondrial MT-TI gene.

MT-TI is a small 69 nucleotide RNA (human mitochondrial map position 4263-4331) that transfers the amino acid isoleucine to a growing polypeptide chain at the ribosome site of protein synthesis during translation.
