Abstract: The present invention provides compositions and methods to facilitate the identification of compounds that are capable of interacting with a biological macromolecule of interest. In one aspect, a composition is provided that comprises an array of one or more types of chemical compounds attached to a solid support, wherein the density of the array of compounds is at least 1000 spots per cm2. In particularly preferred embodiments, these compounds are attached to the solid support through a covalent interaction.

Abstract: The present invention provides a method of synthesizing a library of chemical compounds with skeletal diversity. Two approaches are used to create skeletal diversity within a library of chemical compounds: (1) the “branching pathways” (or reagent-based) approach; and (2) the “folding pathways” (or substrate-based) approach. Upon exposure to certain reaction conditions the members of the library undergo unique transformations into a diverse collection of molecular skeletons, which can be functionalized and derivatized further to generate a large collection of unique, natural product-like compounds. A furan-based library synthesized using the folding pathways approach is provided, and a polycyclic library created using the braching pathways approach is also provided. The invention also provides materials, reagents, intermediates, and kits useful in the practice of the inventive method as well as method for screening the inventive compounds.

Abstract: The present invention concerns the discovery that proteins encoded by a family of genes, termed here HDx-related genes, which are involved in the control of chromatin structure and, thus in transcription and translation. The present invention makes available compositions and methods that can be utilized, for example to control cell proliferation and differentiation in vitro and in vivo.

Abstract: Driven by the influx of data from genome sequencing projects, systematic efforts are now underway to construct defined sets of cloned genes for high throughput expression and purification of recombinant proteins. To facilitate the subsequent study of protein function, the present invention provides protein microarrays that are compatible with the demand for extremely low sample volume and the rapid, simultaneous processing of thousands of proteins, and methods of assaying these arrays. The proteins are covalently or non-covalently attached to the surface of a solid support and retain their ability to interact specifically with other proteins, polynucleotides, other biological macromolecules, or small molecules.

Abstract: The invention provides novel solid supports for the synthesis of compound libraries. The solid supports have the physical capacity to deliver at least 50 nmol of compound and are functionalized with a silicon-containing linker. In one embodiment of the invention the solid support comprises a bead having a diameter of between approximately 400 and 600 &mgr;m functionalized with a silicon-containing linker. According to certain embodiments of the invention the bead is a polystyrene bead. According to certain embodiments of the invention the linker is a diisopropylalkyl-substituted silyl ether. The invention further provides grafted polymeric supports such as lanterns functionalized with a silicon-containing linker.

Abstract: Dimerization and oligomerization of proteins are general biological control mechanisms that contribute to the activation of cell membrane receptors, transcription factors, vesicle fusion proteins, and other classes of intra- and extracellular proteins. We have developed a general procedure for the regulated (inducible) dimerization or oligomerization of intracellular proteins. In principle, any two target proteins can be induced to associate by treating the cells or organisms that harbor them with cell permeable, synthetic ligands. To illustrate the practice of this invention, we have induced: (1) the intracellular aggregation of the cytoplasmic tail of the .zeta.
