: The protein contains specific motifs, including Cysteine Repeat Modular (CRM) domains and EGF-like domains, which are often involved in protein-protein or host-parasite interactions.
: While PCRMP4-deficient sporozoites can still move and invade liver cells (hepatocytes) if manually extracted from oocysts, they are unable to undergo further development or proliferation within the liver. Key Characteristics pcrmp4
PCRMP4 is essential for the transmission of malaria. Its primary known functions include: : The protein contains specific motifs, including Cysteine
: 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. It belongs to a family of four conserved
: Note that PCRMP4 is distinct from pCRMP4 (phosphorylated Collapsin Response Mediator Protein 4), a human protein involved in axonal growth, spinal cord injury response, and certain cancers like pancreatic cancer.
(Plasmodium Cysteine Repeat Modular Protein 4) is a specialized protein found in the Plasmodium genus, the parasites responsible for malaria. It belongs to a family of four conserved proteins (PCRMP1–4) that are critical for the parasite’s ability to transition between its mosquito vector and mammalian hosts. Biological Role and Function
