👉 A microphotin is a type of protein that plays a crucial role in the regulation of cell signaling pathways, specifically by interacting with the GTPase-activating protein (GAP) proteins. These proteins are involved in the activation and deactivation of transcription factors, which in turn regulate gene expression and cellular function within the cell. Microphotins are also known for their ability to bind to and activate the p53 tumor suppressor protein, a critical component of the p21 cycl
