CITED2 (Cbp/p300-Interacting Transactivator With Glu/Asp-Rich Carboxy-Terminal Domain 2): CITED2 is a transcriptional regulator that affects gene expression by interacting with various transcription factors. It plays a crucial role in embryonic development, including the formation of the heart and nervous system, and is involved in cellular responses to hypoxia. Dysregulation of CITED2 is associated with congenital abnormalities and several developmental disorders.
