PHACTR2 (Phosphatase and Actin Regulator 2): PHACTR2 (Phosphatase and Actin Regulator 2) is a gene that governs the regulation of crucial cellular activities, including cell signaling and cytoskeletal dynamics. It encodes a protein that interacts with protein phosphatase 1 (PP1) and actin, contributing to the organisation of actin filaments and the maintenance of cell shape. PHACTR2 plays a role in processes like cell migration and may aid neuronal development.
