PHACTR2 (Phosphatase and Actin Regulator 2): PHACTR2 (Phosphatase and Actin Regulator 2) is a gene that reflects the regulation of key cellular processes, including cell signaling and cytoskeletal dynamics. It encodes a protein that interacts with protein phosphatase 1 (PP1) and actin, playing a role in the organization of actin filaments and the maintenance of cell shape. PHACTR2 is involved in processes such as cell migration and may contribute to neuronal development.
