Predicted to be involved in regulation of response to DNA damage stimulus. Predicted to act upstream of or within several processes, including intracellular signal transduction; negative regulation of mitochondrial outer membrane permeabilization involved in apoptotic signaling pathway; and regulation of nucleobase-containing compound metabolic process. Predicted to be located in mitochondrion. Predicted to be integral component of membrane. Predicted to be active in nucleus. Orthologous to human IER3 (immediate early response 3).
