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).
Leptin is a 167 amino acid protein encoded by the ob gene. It has been found that leptin is produced for the most part in white adipose tissue, with very small amounts being found in brown adipose tissue.Leptin is a four-helix bundle with one very short strand segment and two relatively long interconnected loops.egulator of metabolism. Small amounts of leptin are also secreted by cells in the epithelium, stomach and placenta. Leptin is a protein hormone with important effects in regulating body weight, metabolism and reproductive function.
