A greedy promoter controls malarial var-iations

Cell. 2006 Jan 27;124(2):251-3. doi: 10.1016/j.cell.2006.01.004.

Abstract

Immune evasion by the malaria parasite Plasmodium falciparum is mediated by the mutually exclusive expression of a single member of the var family of genes, which encode variant surface antigens. In a recent paper in Nature, demonstrate that a construct carrying a transcriptionally active var promoter is sufficient to promote allelic exclusion of the parasite's endogenous var gene.
