Three . genes have been identified in human cells, H-., K-., and N-., and they all show a high degree of sequence homology for the first 165 amino acids, after which the sequences diverge. The p21 proteins are attached to the cytopla

They are believed to function as signal switch molecules which relay extracellular growth promoting signals to intracellular targets by cycling between the biologically active ras.GTP and the inactive ras.GDP forms.

Heterotrimeric G-Proteins: α, β, and γ Subunits α (39-52kDa), β (35-36 kDa), and γ (7-10 kDa). They are widely distributed among different tissues and organisms and their structures are highly conserved. This chapter briefly reviews the structure of the cDNAs and the genes for various G-protein α, β, and γ subunits from mammalian cells and the occurrence of G-protein genes in lower eukaryotes.
