Predicted to enable several functions, including protein C-terminus binding activity; protein N-terminus binding activity; and protein dimerization activity. Involved in several processes, including cellular response to hypoxia; cellular response to retinoic acid; and negative regulation of apoptotic process. Located in mitochondrion and nucleus. Is active in several cellular components, including GABA-ergic synapse; glutamatergic synapse; and postsynaptic density. Colocalizes with axon. Orthologous to human PHB2 (prohibitin 2).
