The Rho family refers to a group of proteins that play a crucial role in various cellular processes, including cell movement, shape, and division. These proteins are part of the larger GTPase superfamily and are known for their ability to bind and hydrolyze GTP, which is essential for their function in signaling pathways. Rho proteins are involved in regulating the cytoskeleton, which provides structural support to cells. They are also important in processes like cell adhesion and cell migration, making them significant in development, immune responses, and wound healing. Dysregulation of Rho family proteins can contribute to various diseases, including cancer.
