Translationally Controlled Tumor Protein (TCTP)

Target
TCTP
Molecular classification

01

Overview

Translationally controlled tumor protein (TCTP) is a highly conserved, multifunctional protein found in Plasmodium falciparum. It is involved in cell proliferation, apoptosis inhibition, and modulation of host immune responses. PfTCTP can be secreted into the bloodstream, acting as a histamine-releasing factor and interacting with host immune cells. It also binds hemin and interacts with dihydroartemisinin, potentially impacting drug action. Its role in immunopathology and drug interactions makes it a potential therapeutic target.
