Predicted to be involved in snRNA transcription by RNA polymerase II. Predicted to act upstream of or within positive regulation of transcription elongation from RNA polymerase II promoter and transcription elongation from RNA polymerase II promoter. Predicted to be located in nucleoplasm. Predicted to be part of transcription elongation factor complex. Is expressed in several structures, including branchial arch; eye; inner ear; limb ectoderm; and maxillary process. Orthologous to human ELL2 (elongation factor for RNA polymerase II 2).
