Control of the energetics and specificity of DNA binding polyamides is necessary for inhibition of protein-DNA complex formation and gene regulation studies. Typically, solid-phase methods using Boc monomers for synthesis have depended on Boc-beta-Ala-PAM resin which affords a beta-alanine-Dp tail at the C-terminus, after cleavage with(More)
The pink-eyed dilution protein (P-protein) plays a critical role in melanin synthesis in melanocytes and retinal pigment epithelium cells. Mutation in this protein may cause complete or partial albinism. Role of the P-protein ranges in melanin synthesis to maturation and trafficking of the melanosomes. The aim of the present study was to evaluate the effect(More)
BACKGROUND Most transcriptional activators minimally comprise two functional modules, one for DNA binding and the other for activation. Several activators also bear an oligomerization region and bind DNA as dimers or higher order oligomers. In a previous study we substituted these domains of a protein activator with synthetic counterparts [Mapp et al.,(More)
Side-by-side pairs of three five-membered rings, N-methylpyrrole (Py), N-methylimidazole (Im), and N-methylhydroxy-pyrrole (Hp), have been demonstrated to distinguish each of the four Watson Crick base pairs in the minor groove of DNA. However, not all DNA sequences targeted by these pairing rules achieve affinities and specificities comparable to DNA(More)
