Abstract: The present invention relates to regulation of cellular proliferation. More particularly, the present invention is directed to nucleic acids encoding SAK, which is a protein kinase involved in modulation of cellular proliferation and cell cycle regulation. The invention further relates to methods for identifying and using agents, including small molecule chemical compositions, antibodies, peptides, cyclic peptides, nucleic acids, RNAi, antisense nucleic acids, and ribozymes, that modulate cell cycle regulation and cellular proliferation via modulation of SAK; as well as to the use of expression profiles and compositions in diagnosis and therapy related to cell cycle regulation and modulation of cellular proliferation, e.g., for treatment of cancer and other diseases of cellular proliferation.

Abstract: Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases. The activities of those Ntn having multiple activities can be differentially inhibited by the compounds described. For example, the chymotrypsin-like and PGPH activities of the 20S proteasome can be selectively inhibited with the inventive compounds. The peptide-based compounds include at least three peptide units, an epoxide or aziridine, and functionalization at the N-terminus, such as a detectable label. Along with therapeutic utilities, these peptide based compounds can be used in assays useful for screening, monitoring, diagnostic and/or dosing purposes.

Abstract: A novel protein which interacts with ras p21, has been identified. This protein, RGL, shares 69% amino acid homology with ral guanine nucleotide dissociation stimulator (ralGDS). ralGDS was also found to bind ras p21. The ras p21-interacting domain of RGL (RID) bound to ras p21 through the effector loop of ras p21. Polypeptide and polynucleotide compositions of the RGL protein are provided as well as methods for implementing the diagnostic and therapeutic uses of these compositions. The uses include isolating effector proteins of ras p21 and modulating ras activity.
