ABSTRACT
Farnesylation is an important post-translational protein modification in eukaryotes. Farnesylation is performed by protein farnesyltransferase, a heterodimer composed of an α- (FTα) and a ß-subunit. Recently, homodimerization of truncated rat and yeast FTα has been detected, suggesting a new role for FTα homodimers in signal transduction. We investigated the putative dimerization behaviour of human and rat FTα. Different in vitro and in vivo approaches revealed no self-dimerization and a presumably artificial formation of homotrimers and higher homo-oligomers in vitro. Our study contributes to the clarification of the physiological features of FTase in different species and may be important for the ongoing development of FTase inhibitors.
