: PCRMP4 is not required for the parasite's survival during the blood-stage of infection (the stage that causes symptoms in humans), but it is absolutely necessary for completing the complex life cycle through the mosquito. Research and Medical Context
: Although PCRMP4-deficient parasites are severely impaired in the liver, experiments have shown that immunization with these live, genetically-attenuated sporozoites does not induce a strong protective immune response compared to other attenuated strains. pcrmp4
: Parasites lacking PCRMP4 fail to invade the mosquito's salivary glands, preventing them from being transmitted to a host during a mosquito bite. : PCRMP4 is not required for the parasite's

: Research involving Plasmodium berghei (a rodent malaria model) showed that deleting the pcrmp4 gene resulted in parasites that could form normal oocysts but could not progress further in the transmission cycle.
: PCRMP4 is required for sporozoites (the infectious stage of the parasite) to exit the oocyst—a cyst-like structure on the mosquito's midgut wall.
