Predicted to enable interleukin-2 receptor binding activity; phosphoprotein phosphatase activity; and ribonucleoprotein complex binding activity. Predicted to be involved in mitochondrial membrane organization; protein dephosphorylation; and protein import into mitochondrial matrix. Predicted to act upstream of or within release of cytochrome c from mitochondria. Predicted to be located in mitochondrial inner membrane and nuclear speck. Predicted to be part of TIM23 mitochondrial import inner membrane translocase complex. Human ortholog(s) of this gene implicated in 3-methylglutaconic aciduria type 9. Orthologous to human TIMM50 (translocase of inner mitochondrial membrane 50). [provided by Alliance of Genome Resources, Apr 2022]
