The novel complex is distinct from that described previously as binding to B cell enhancer sites and can be formed by addition of PU.1 to extracts from certain nonmyeloid cell types which do not express PU.1 , including T cells and epithelial cells , but not from erythroid cells .
 protein: PU.1; DNA: B cell enhancer sites; cell type: erythroid cells; protein: PU.1; cell type: T cells; cell type: epithelial cells; cell type: nonmyeloid cell types
