PHACTR4

PHACTR4 (Phosphatase and Actin Regulator 4): PHACTR4 is a multifunctional protein involved in the regulation of cellular signaling pathways and cytoskeletal dynamics. As a member of the PHACTR family, it exerts its effects through interactions with protein phosphatase 1 (PP1) and actin filaments. PHACTR4 has been implicated in various cellular processes, including cell cycle progression, cell migration, and neuronal development. Its role in modulating PP1 activity suggests involvement in the regulation of diverse cellular functions, including gene expression and metabolism. Additionally, PHACTR4 has been associated with cardiovascular diseases, particularly coronary artery disease, where it influences endothelial function and vascular remodeling. The intricate interplay between PHACTR4, PP1, and actin dynamics underscores its importance in cellular physiology and pathology. Understanding the molecular mechanisms governed by PHACTR4 holds promise for elucidating its therapeutic potential in diseases ranging from cancer to cardiovascular disorders.
