Enables chromatin binding activity. Involved in several processes, including cellular response to lipopolysaccharide; endodermal cell fate commitment; and negative regulation of transcription by RNA polymerase II. Part of Cdc73/Paf1 complex. Is expressed in cerebral cortex; early conceptus; and genitourinary system. Orthologous to human PAF1 (PAF1 homolog, Paf1/RNA polymerase II complex component).
