To understand the function of AML1 during B cell differentiation , we analyzed regulatory regions of B cell-specific genes for potential AML1 -binding sites and have identified a putative AML1 -binding site in the promoter of the B cell-specific tyrosine kinase gene, blk .
 ( protein: AML1, None) , ( DNA: regulatory regions, None) , ( DNA: AML1 -binding sites, None) , ( protein: AML1, None) , ( protein: AML1, None) , ( DNA: AML1 -binding site, None) , ( DNA: B cell-specific tyrosine kinase gene, blk, None) , ( cell type: B cell, None) , ( DNA: B cell-specific genes, None)
