The SLC25A4 gene provides the instructions for making a protein called adenine nucleotide translocase type 1 (ANT1).ANT1 functions in mitochondria, which are structures within cells that convert the energy from food into a form that cells can use.he SLC25A4 gene provides the instructions for making a protein called adenine nucleotide translocase type 1 (ANT1).
For instance, let's take hemoglobin. It generally has 146 amino acids, but not all them are essential for the protein to be functional. So, if we a ask a question as to how many different amino acids are necessary for the protein to be known as the  hemoglobin  protein, then the answer depends on many things. Whenever changes in amino acid affects the physical structure of protein molecule, the affected protein becomes inactive.
