## Abstract Mitochondria and crude nuclei containing fractions from human placenta have been shown to contain proteins which bind [Ξ±^32^P]βGTP. Prior to this study the number of GTPβbinding proteins in placental nuclei and their nucleotide specificity was not known. Also unknown was the identity of

## Abstract Rho/Rac proteins constitute a subgroup of the Ras superfamily of GTP hydrolases. Although originally implicated in the control of cytoskeletal events, it is currently known that these GTPases coordinate diverse cellular functions, including cell polarity, vesicular trafficking, the cell
## Abstract Recent studies have shown that GTPβbinding proteins can modulate mitochondrial membrane fusion and fission. Furthermore, GTPβbinding proteins can regulate the binding of ribosomes to the mitochondrial membrane and may facilitate the import of proteins through contact points between inne
Three GTPβbinding proteins with apparent molecular masses of 27, 28 and 30 kDa have been detected in isolated nuclei of etiolated pea plumules. After LDSβPAGE and transfer to nitrocellulose these proteins bind [^32^p]GTP in the presence of excess ATP, suggesting that they are monomeric G proteins. W
