Schizosaccharomyces pombe
The solution structure of TCTP from yeast, "Schizosaccharomyces pombe" has been determined by NMR spectroscopy which indicated that this protein is structurally similar to two small guanine nucleotide-free chaperones, namely Mss4 and Dss4. TCTP and Mss4/Dss4 are now therefore structurally grouped into one protein superfamily.
