Predicted to enable RNA polymerase II C-terminal domain phosphoserine binding activity; S-adenosyl-L-methionine binding activity; and mRNA (2'-O-methyladenosine-N6-)-methyltransferase activity. Involved in mRNA methylation. Predicted to be located in intercellular bridge; microtubule cytoskeleton; and nucleoplasm. Predicted to be active in nucleus. Orthologous to human PCIF1 (phosphorylated CTD interacting factor 1). [provided by Alliance of Genome Resources, Apr 2022]
