Enables 14-3-3 protein binding activity. Involved in intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator. Acts upstream of or within several processes, including cellular response to dexamethasone stimulus; negative regulation of TOR signaling; and negative regulation of glycolytic process. Located in mitochondrion. Is expressed in reproductive system and retina nuclear layer. Orthologous to human DDIT4 (DNA damage inducible transcript 4).
