Genes affected

MT-RNR1 (HGNC:7470): (mitochondrially encoded 12S RNA) Enables DNA binding activity and DNA-binding transcription factor binding activity. Involved in several processes, including osteoblast proliferation; regulation of carbohydrate utilization; and regulation of phosphate metabolic process. Located in extracellular space; mitochondrion; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

TRNV (HGNC:7500): (mitochondrially encoded tRNA valine)

MT-RNR2 (HGNC:7471): (mitochondrially encoded 16S RNA) Enables G protein-coupled receptor binding activity; protein self-association; and receptor antagonist activity. Involved in several processes, including leukocyte chemotaxis; negative regulation of cell death; and negative regulation of neuroinflammatory response. Located in several cellular components, including mitochondrion; perinuclear region of cytoplasm; and sperm midpiece. [provided by Alliance of Genome Resources, Apr 2022]
