Nuclear localization signal and phosphorylation of Serine350 specify intracellular localization of DRAK2.

DAP kinase-related apoptosis-inducing kinase 2 (DRAK2) is a serine/threonine kinase of the death-associated protein kinase family. DRAK2 mediates apoptosis induced by extracellular stimuli, including UV irradiation and interleukin-2, and also regulates T-cell receptor sensitivity in developing thymocytes. During these events, the subcellular localization of DRAK2 changes between the nucleus and cytoplasm.
