Cytoplasmic ATM protein kinase: an emerging therapeutic target for diabetes, cancer and neuronal degeneration

Download Type: Adobe PDF

In this article Da-Qing Yang, Marie-Jo Halaby, Yan Li, Jody C. Hibma and Paul Burn discuss recent advances in elucidating the cytoplasmic localization and function of ATM. Particular attention is given to the role of ATM in insulin signaling and Akt activation. The potential for cytoplasmic ATM protein kinase to be an emerging therapeutic target for treating diabetes, cancer and neuronal degeneration is discussed.

Ataxia–telangiectasia (A–T) is an autosomal recessive disorder characterized by cerebellar ataxia and oculocutaneous telangiectasias. The gene mutated in this disease, Atm (A–T mutated), encodes a serine/threonine protein kinase that has been traditionally considered to be a nuclear protein controlling cellcycle progression. However, many of the growth abnormalities observed in patients with A–T, including neuronal degeneration and insulin resistance, remain difficult to explain with nuclear localization of ATM.
