Translationally controlled tumor protein (TCTP) is often designated as a stress-related protein because of its highly regulated expression in stress conditions. Following a thermal shock, TCTP expression is highly upregulated in a variety of cells. However, at present it is not known whether this upregulation has any cell protective function similar to other heat shock proteins. In this study human TCTP (HuTCTP) and a TCTP homolog (SmTCTP) from Schistosoma mansoni were evaluated for heat shock protein-like function and molecular chaperone activity. Our results show that similar to other molecular chaperones, both human and parasite TCTPs can bind to a variety of denatured proteins and protect them from the harmful effects of thermal shock. An important observation was the ability of both HuTCTP and SmTCTP to bind to native protein and protect them from thermal denaturation. Over expression of TCTP in bacterial cells protected them from heat shock-induced death. These findings suggest that TCTP may belong to a novel small molecular weight heat shock protein.
