Dual Roles of Serine-Threonine Kinase Receptor-Associated Protein (STRAP)‎ in Redox-Sensitive Signaling Pathways Related to Cancer Development

Abstract EN

Serine-threonine kinase receptor-associated protein (STRAP) is a transforming growth factor β (TGF-β) receptor-interacting protein that has been implicated in both cell proliferation and cell death in response to various stresses.

However, the precise roles of STRAP in these cellular processes are still unclear.

The mechanisms by which STRAP controls both cell proliferation and cell death are now beginning to be unraveled.

In addition to its biological roles, this review also focuses on the dual functions of STRAP in cancers displaying redox dysregulation, where it can behave as a tumor suppressor or an oncogene (i.e., it can either inhibit or promote tumor formation), depending on the cellular context.

Further studies are needed to define the functions of STRAP and the redox-sensitive intracellular signaling pathways that enhance either cell proliferation or cell death in human cancer tissues, which may help in the development of effective treatments for cancer.
