Together these data demonstrate that the v-abl protein specifically interferes with light-chain gene rearrangement by suppressing at least two pathways essential for this stage of B-cell differentiation and suggest that tyrosine phosphorylation is important in regulating RAG gene expression .
 ( protein: v-abl protein, None) , ( DNA: light-chain gene, None) , ( DNA: RAG gene, None) , ( cell type: B-cell, None)
