Predicted to enable several functions, including RNA binding activity; nuclear receptor coactivator activity; and tRNA pseudouridine synthase activity. Predicted to be involved in mRNA pseudouridine synthesis and tRNA pseudouridine synthesis. Predicted to act upstream of or within positive regulation of transcription by RNA polymerase II. Predicted to be located in mitochondrion; nucleolus; and nucleoplasm. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in myopathy, lactic acidosis, and sideroblastic anemia 1. Orthologous to human PUS1 (pseudouridine synthase 1).
