Description

Mammalian translationally controlled tumour protein (TCTP) (or P23) is a protein which has been found to be preferentially synthesised in cells during the early growth phase of some types of tumour
[1, 2]
, but which is also expressed in normal cells. The physiological function of TCTP is still not known. It was first identified as a histamine-releasing factor, acting in IgE +-dependent allergic reactions. In addition, TCTP has been shown to bind to tubulin in the cytoskeleton, has a high affinity for calcium, is the binding target for the antimalarial compound artemisinin, and is induced in vitamin D-dependent apoptosis. TCTP production is thought to be controlled at the translational as well as the transcriptional level
