>TIGR01477 RIFIN variant surface antigen, rifin family; InterPro: IPR006373 Malaria is still a major cause of mortality in many areas of the world. Plasmodium falciparum causes the most severe human form of the disease and is responsible for most fatalities. Severe cases of malaria can occur when the parasite invades and then proliferates within red blood cell erythrocytes. The parasite produces many variant antigenic proteins, encoded by multigene families, which are present on the surface of the infected erythrocyte and play important roles in virulence. A crucial survival mechanism for the malaria parasite is its ability to evade the immune response by switching these variant surface antigens. The high virulence of P. falciparum relative to other malarial parasites is in large part due to the fact that in this organism many of these surface antigens mediate the binding of infected erythrocytes to the vascular endothelium (cytoadherence) and non-infected erythrocytes (rosetting). This can lead to the accumulation of infected cells in the vasculature of a variety of organs, blocking the blood flow and reducing the oxygen supply. Clinical symptoms of severe infection can include fever, progressive anaemia, multi-organ dysfunction and coma. For more information see . This entry represents the rifin family of variant surface antigens, encoded by the rif (short for "repetetive interspersed family") genes. This is the largest variant surface antigen family in P. falciparum, with roughly 150 genes present in the genome of this parasite . The function of these proteins is not yet known, but rifins are strongly immunogenic and high levels of anti-rifin antibodies are correlated with rapid parasite clearance and asymptomatic infections . .
