Protein: Patatin-like phospholipase 1 (EC 3.1.1.4) (PfPATPL1) (W7K139)
Organism: Plasmodium falciparum (isolate NF54)
Function: Hydrolyzes the ester bond of the fatty acyl group attached at the sn-2 position of phospholipids such as phosphatidylcholine. Involved in gametogenesis; however, it is not clear whether it is involved in gametocytes development in host erythrocytes or in gametocyte activation in the mosquito midgut. Involved in gametocyte development in host erythrocytes; however, not involved in gametocytes activation including male gamete exflagellation. Involved in the rounding up of gametocytes following activation in the mosquito midgut; however, not required for gametocyte development in host erythrocytes. Required for exflagellation of activated male gametocytes. Involved in gametocytes egress from host erythrocytes by promoting the relocalization of perforin-like protein PLP2-containing vesicles to the periphery of gametocytes; PLP2 secretion is required for permeabilization of the erythrocyte membrane and thus, promotes gametocyte egress. Dispensable for asexual blood stage development.
