[Receptors--one component of intercellular communication pathways]

Every event, which occurs in the cell, can be an information capable to propagate. The existence of the structures which are capable of transmission (i.e. RECEPTORS) is necessary for the effective signal propagation. In this review the receptors are divided according their localization in the cell, genetic and structural similarity to cytoplasmatic, organelic and membrane receptors. Structure and function (including basic characteristics of intracellular signalization) of the main representatives of the previously mentioned groups are described. The possible interactions between receptors are mentioned too.
