ATP synthase membrane subunit f pseudogene 4 (ATP5MFP4)

ATP synthase membrane subunit f pseudogene 4 (ATP5MFP4) is a nonfunctional, transcribed or non-transcribed pseudogene related to the mitochondrial ATP synthase subunit f gene. ATP synthase is a multi-subunit enzyme complex in mitochondria essential for ATP production. While the true subunit f in active ATP synthase plays a role in membrane association and energy coupling, pseudogenes like ATP5MFP4 do not contribute to known biological processes or disease states, and are not considered functional targets for pharmacologic intervention[2][3]. Key clarification: “ATP synthase membrane subunit f” is a real membrane protein and a component of the mitochondrial ATP synthase complex V, involved in cellular energy production[3]. Its genuine gene is ATP5MF. However, *ATP5MFP4* is a pseudogene—an inactivated copy that does not encode an active protein product[2]. For further structured annotation, ATP5MFP4 should be cataloged as a **pseudogene** and **not an actionable drug target**. If you are seeking a real target, consider ATP synthase membrane subunit f (ATP5MF), not its pseudogene.
