Predicted to enable transcription elongation regulator activity. Predicted to be involved in positive regulation of transcription, DNA-templated and regulation of transcription elongation from RNA polymerase II promoter. Predicted to act upstream of or within positive regulation of transcription by RNA polymerase II. Predicted to be located in intercellular bridge and nuclear body. Predicted to be part of transcription elongation factor complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human EAF1 (ELL associated factor 1). [provided by Alliance of Genome Resources, Apr 2022]
