Predicted to enable RNA binding activity; RNA polymerase II complex binding activity; and identical protein binding activity. Predicted to be involved in negative regulation of protein kinase activity; positive regulation of transcription by RNA polymerase II; and tRNA splicing, via endonucleolytic cleavage and ligation. Predicted to be located in microtubule cytoskeleton; nucleoplasm; and perinuclear region of cytoplasm. Predicted to be part of tRNA-splicing ligase complex. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and respiratory system. Orthologous to human RTRAF (RNA transcription, translation and transport factor). [provided by Alliance of Genome Resources, Apr 2022]
