Predicted to enable DNA binding activity; translation elongation factor activity; and zinc ion binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within transcription elongation by RNA polymerase II and translational elongation. Predicted to be active in nucleus. Is expressed in lens; olfactory placode; and peripheral olfactory organ. Orthologous to human TCEA2 (transcription elongation factor A2).
