NR2F2 (Nuclear Receptor Subfamily 2 Group F Member 2): NR2F2 is a transcription factor, also known as COUP-TFII, that plays a crucial role in the development and function of multiple organs, including the heart and vascular system. It regulates genes involved in angiogenesis (the formation of new blood vessels) and metabolic processes. Abnormal NR2F2 activity is linked to developmental disorders and certain cancers, where it can influence tumor growth and metastasis.
