Acts upstream of or within cranial ganglion development; regulation of apoptotic process; and regulation of response to oxidative stress. Predicted to be located in mitochondrion. Predicted to be active in nucleus. Is expressed in several structures, including blastomere; liver; nervous system; pleuroperitoneal region; and prechordal plate. Human ortholog(s) of this gene implicated in cerebellar hyplasia/atrophy, epilepsy, and global developmental delay. Orthologous to human OXR1 (oxidation resistance 1).
