PROBLEM:  Our results implicate an internal bipartite nuclear localizing sequence as a regulatory domain that modulates 5 - lipoxygenase redistribution and catalysis in granulocytic cells .

SOLUTION: 5 - lipoxygenase

PROBLEM:  Further , we find that HEB driven by the endogenous E2A promoter can functionally replace E2A in supporting B - cell commitment and differentiation toward completion .

SOLUTION:
endogenous E2A promoter
