Location of the MT-RNR2 gene on the H strand of the human mitochondrial genome. MT-RNR2, or RRNL, is one of the two mitochondrial ribosomal RNA genes (blue boxes).

Mitochondrially encoded 16S RNA (often abbreviated as 16S) is the mitochondrial large subunit ribosomal RNA[1][2] that in humans is encoded by the MT-RNR2 gene. The MT-RNR2 gene also encodes the Humanin polypeptide that has been the target of Alzheimer's disease research.[3]

The 16S rRNA is the mitochondrial homologue of the prokaryotic 23S and eukaryotic nuclear 28S ribosomal RNAs.[4]
