Function

ARF1_PLAF7 Small GTPase involved in protein trafficking between different compartments (PubMed:21045287). Modulates vesicle budding and uncoating within the Golgi complex (By similarity). In its GTP-bound form, triggers the recruitment of coatomer proteins to the Golgi membrane (By similarity). The hydrolysis of ARF1-bound GTP, which is mediated by ARFGAPs proteins, is required for dissociation of coat proteins from Golgi membranes and vesicles (By similarity). Regulates the transport of N-acylated AK2 to the parasitophorous vacuole membrane (PubMed:33604307). May be involved in the activation of lipid kinase PIP5K (PubMed:19171150).[UniProtKB:P84077][1] [2] [3]

Publication Abstract from PubMed

Vesicular trafficking may play a crucial role in the pathogenesis and survival of the malaria parasite. ADP-ribosylation factors (ARFs) are among the major components of vesicular trafficking pathways in eukaryotes. The crystal structure of ARF1 GTPase from Plasmodium falciparum has been determined in the GDP-bound conformation at 2.5 A resolution and is compared with the structures of mammalian ARF1s.
