title: [The problem of polymorphism of GTP-binding protein subunits and its evolutionary aspects].
abstract: The data about multiplicity of isoforms of the GTP-binding protein alpha-subunits are analyzed from the point of view of their origin, functional purpose and appearance in the course of onto- and phylogenesis. An assumption is made that the polymorphism of GTP-binding protein subunits can be regarded as an important regulatory mechanism which appeared at rather late stages of evolution.
