title: [Using peptide strategy for study functions and structure of signal proteins with enzymatic activity].
abstract: The peptide strategy, a new direction of molecular endocrinology, includes the synthesis of peptides corresponding to functional regions of signal proteins, the use of the peptides for study of the molecular mechanisms of transduction of hormonal signal into cell ant the development of selective regulators of hormonal signaling systems on the basis of these peptides. The peptide strategy is used for study a wide spectrum of the proteins, components of signal systems, the proteins possessing the catalytic activity in particular, such as tyrosine kinases receptors, the enzymes generating the second messengers, serine/threonine protein kinase, phosphatases. In the first time in the review the data concerning the synthetic peptides, derivatives of the primary structure of proteins with the enzymatic activity, their application for study of the structural-functional organization and the molecular mechanisms of action of signal proteins, and the construction of regulators of fundamental cell processes on the basis of these peptides are analyzed and summarized.
