Thrombospondin binds falciparum malaria parasitized erythrocytes and may mediate cytoadherence.

abstract：:Post-translational modification (PTM) of proteins plays an important part in mediating protein interactions and/or the recruitment of specific protein targets. PTM can be mediated by the addition of functional groups (for example, acetylation or phosphorylation), peptides (for example, ubiquitylation or sumoylation), ...
