 AB    Transcriptional regulation involves the interaction of enhancer-promoter
       regions with cellular binding proteins. NF-kB is a nuclear
       transcriptional factor which binds and mediates transcription from the
       sequences in the promoter region. In our system we have studied NF-kB
       and related proteins in PHA stimulated cord blood mononuclear cells. In
       this model the cells were treated with rIL2 and with or without
       DEAE-dextran, and nuclear extracts were made. Binding of NF-kB enhancer
       region sequences with these extracts were studied by gel shift assays.
       As well as NF-kB, another protein NF-TIM was detected in large amounts.
       This NF-TIM also binds to NF-kB region even when it is mutated (GGG to
       CTC) but binding is decreased with double mutated enhancer (GGG to CTC
       and CCG to AAC). Further studies of the role of NF-TIM in HIV-1
       replication are in progress with UV crosslinking, footprinting, and
       cloning of enhancer region and its mutants in a reporter gene system.
