PIWI proteins

PIWI proteins are specialized molecules inside our cells that help regulate gene expression, particularly in the activity of tiny RNA molecules called piRNAs. These proteins play a crucial role in protecting the integrity of our genetic information by preventing the activity of harmful genetic elements like transposons, which can move around and damage DNA. Found mainly in reproductive cells, PIWI proteins are essential for maintaining fertility and normal development. They form part of the cell’s natural defense system, ensuring that genetic information remains stable and functions correctly across generations.
