sentences:  Recently, the structure of TCTP was determined and exhibited significant structural similarity to the human protein Mss4, which is a guanine nucleotide-free chaperone of the Rab protein.Translationally controlled tumor protein (TCTP) is a highly conserved protein found in eukaryotes, across animal and plant kingdoms and even in yeast.Close homologues have been found in plants, earthworm, "Caenorhabditis elegans" (F52H2.11), Hydra, "Saccharomyces cerevisiae" (YKL056c) , "Schizosaccharomyces pombe" (SpAC1F12.02c) and protozoa like "Trypanosoma brucei" .
