Vital role for the Plasmodium actin capping protein (CP) beta-subunit in motility of malaria sporozoites
Summary Successful malaria transmission from the mosquito vector to the mammalian host depends crucially on active sporozoite motility. Sporozoite locomotion and host cell invasion are driven by the parasite's own actin/myosin motor. A unique feature of this motor machinery is the presence of very short subpellicular actin filaments. Therefore, F-actin stabilizing proteins likely play a central...
متن کاملcDNAs encoding the beta subunit of cap Z, the actin-capping protein of the Z line of muscle.
Three cDNAs encoding the beta chain of Cap Z have been isolated from lambda gt11 chicken libraries screened with antibodies. The coding region, which is identical among the cDNAs, contains 831 basepairs encoding a protein with 277 amino acid residues and Mr = 31,352. The predicted protein sequence contains eight regions that match perfectly the NH2-terminal sequence of eight peptides isolated f...
متن کاملMammalian CARMIL inhibits actin filament capping by capping protein.
Actin polymerization in cells occurs via filament elongation at the barbed end. Proteins that cap the barbed end terminate this elongation. Heterodimeric capping protein (CP) is an abundant and ubiquitous protein that caps the barbed end. We find that the mouse homolog of the adaptor protein CARMIL (mCARMIL) binds CP with high affinity and decreases its affinity for the barbed end. Addition of ...
متن کاملCapping protein binding to actin in yeast
The mechanism by which capping protein (CP) binds barbed ends of actin filaments is not understood, and the physiological significance of CP binding to actin is not defined. The CP crystal structure suggests that the COOH-terminal regions of the CP alpha and beta subunits bind to the barbed end. Using purified recombinant mutant yeast CP, we tested this model. CP lacking both COOH-terminal regi...
متن کاملDifferential localization and sequence analysis of capping protein beta- subunit isoforms of vertebrates
Capping protein nucleates the assembly of actin filaments and stabilizes actin filaments by binding to their barbed ends. We describe here a novel isoform of the beta subunit of chicken capping protein, the beta 2 isoform, which arises by alternative splicing. The chicken beta 1 isoform and the beta 2 isoform are identical in their amino acid sequence except for a short region at the COOH termi...
