Figure 1.

Gene structures and chromosomal locations of human protein prenyltransferase subunit genes. The chromosome diagrams and the locations of the genes on the cytogenetic map are according to the NCBI MapViewer [67]. The sizes of the genes are indicated but are not drawn to scale. (a) Genes encoding CaaX protein prenyltransferases are relatively long; (b) genes encoding non-CaaX protein prenyltransferases are much shorter.
