What is the normal function of the MT-RNR1 gene?
The MT-RNR1 gene provides instructions for making a particular type of RNA, a molecule that is a chemical cousin of DNA. This type of RNA, known as ribosomal RNA (rRNA), is involved in the assembly of proteins within cells.
The MT-RNR1 gene provides instructions for a specific form of ribosomal RNA called 12S RNA, which is present only in cellular structures called mitochondria. These structures convert energy from food into a form that cells can use. Through a process called oxidative phosphorylation, mitochondria use oxygen and simple sugars to create adenosine triphosphate (ATP), the cell's main energy source. 12S RNA molecules help assemble protein building blocks (amino acids) into the functioning proteins that carry out oxidative phosphorylation.
How are changes in the MT-RNR1 gene related to health conditions?
Where is the MT-RNR1 gene located?
