PRR29 (proline-rich protein 29) is a protein encoded by the PRR29 gene located in humans on chromosome 17 at 17q23.
Its function is not fully understood. Its name is derived from the chain of 5 proline amino acids located toward the end of the protein. The primary domain within the sequence of this protein is known as DUF4587. It is reported to have high levels of expression in tissues pertaining to the circulatory system and the immune system. It is hypothesized that PRR29 is a nuclear protein that facilitates communication between the nucleus and the mitochondria.
The gene is also commonly known as C17orf72. The gene has a size of 5961 base pairs and contains five exons.
