Predicted to enable identical protein binding activity. Predicted to be involved in mRNA methylation and regulation of alternative mRNA splicing, via spliceosome. Predicted to act upstream of or within RNA splicing and mRNA processing. Located in cytoplasm and nucleoplasm. Part of RNA N6-methyladenosine methyltransferase complex. Is expressed in several structures, including early conceptus; embryo mesoderm; genitourinary system; hemolymphoid system gland; and liver. Orthologous to human WTAP (WT1 associated protein).
