Abstract: The present invention provides FK228 analogs and methods of making and using the same. Such analogs are potent inhibitors of histone deacetylase and, in certain embodiments, are capable of specifically targeting cancerous cells and tissues. In preferred embodiments, these analogs are characterized by a cyclic disulfide design.

Abstract: The invention provides a method of a method of characterizing the proliferative state of cells in a biological sample based on detecting transcription factor-mediated phosphorylation of histone H2B (H2B) at residue 36 (numbered according to human H2B). This method optionally includes detection of transcription factor-mediated acetylation of histone H3 (H3) at residue 14 and/or acetylation of histone H4, which also provides an indication of cell proliferation. The invention also provides antibodies specific for H2B phosphorylated at H2B; transcription factor and H2B derivatives and related polynucleotides, vectors, host cells, recombinant production methods and compositions; and screening methods for modulators of H2B phosphorylation at residue 36.

Abstract: The kinase suppressor of Ras (Ksr), a novel protein kinase involved in the regulation of cell growth and differentiation, provides an important target for therapeutic intervention. The subject compositions also include nucleic acids which encode a Ksr kinase, and hybridization probes and primers capable of hybridizing with a Ksr gene. Such probes are used to identify mutant Ksr alleles associated with disease. The invention includes methods, including phosphorylation and binding assays, for screening chemical libraries for lead compounds for a pharmacological agent useful in the diagnosis or treatment of disease associated Ksr activity or Ksr-dependent signal transduction.
