The thesis carries information on the studies conducted by X ray crystallography and the nuclear magnetic resonance on the domain organization of different proteins and their structural necessities for binding to their respective partners. The crystal structure of the human 14-3-3sigma protein was solved at a resolution of 2.8 Å and compared it to the known structures of 14-3-3zeta and 14-3-3tau. The interactions of CDK6, p19, and MyoD peptides, CDK2-cyclin A2, and its binding partners: p53, pRb and p27 have been tested using in vitro biophysical and biochemical methods. The interactions between pRb, p27, and p53 with CDK2-cyclin A2, CDK6 and p19 were documented. The structure of the complex of the N-terminal domain of IGFBP-4 (NBP-4, residues, 1-92) and IGF-I emphasizes a critical role of the first amino-terminal residues of IGFBPs for IGF signaling.
