Unique Identifier : AIDSLINE ASHM5/94348916 AB An investigation into the characterisation of mammalian nuclear proteins which bind to the HIV-1 LTR U3 region has been carried out using a series of overlapping 40-mer oligonucleotides. These oligonucleotides were synthesised to correspond to the HXB2 sequence from n.t. -210 to n.t. -454. Two oligonucleotides have shown a number of specific binding interactions in mobility shift assays, U.V. cross-linked mobility shift assays and south-western analysis. Oligonucleotide 7 (n.t. -210 to n.t. -250) has at least 4 specific interactions and oligonucleotide 13(n.t. -410 to n.t. 454) has at least 2 specific interactions. The region of oligonucleotide 7 is thought to bind ILF (Li et al, 1991) and possibly members of the ets family. No protein binding has been reported in the region of oligonucleotide 13.
