BACKGROUND The allergenic profile of patients hypersensitive to pollen pan-allergens, profilin and polcalcin, has received little attention so far. OBJECTIVE To detect whether hypersensitivity to profilin and polcalcin follows sensitization to specific allergen sources or represents a primary phenomenon, and to examine the sensitization profiles of patients hypersensitive to pollen pan-allerg...
The organization of actin filaments into large ordered structures is a tightly controlled feature of many cellular processes. However, the mechanisms by which actin filament polymerization is initiated from the available pool of profilin-bound actin monomers remain unknown in plants. Because the spontaneous polymerization of actin monomers bound to profilin is inhibited, the intervention of an ...
Background: Allergy is a clinical disorder affecting humans worldwide. Allergenic extracts prepared from natural source materials remain heterogeneous in composition and content, but are regularly used for diagnosis and immunotherapy. Recombinant allergens are suitable candidates to use in place of natural allergens; however, the recombinant allergens should be assessed and compared with the na...
Profilin is an actin monomer-binding protein implicated in the polymerization of actin filaments. In the budding yeast Saccharomyces cerevisiae, the pfy1-111 rho2delta double mutant has severe growth and actin cytoskeletal defects. The GEA1 and GEA2 genes, which code for paralog guanosine exchange factors for Arf proteins, were identified as multicopy suppressors of the mutant phenotype. These ...
Like animal cells, fission yeast divides by assembling actin filaments into a contractile ring. In addition to formin Cdc12p and profilin, the single tropomyosin isoform SpTm is required for contractile ring assembly. Cdc12p nucleates actin filaments and remains processively associated with the elongating barbed end while driving the addition of profilin-actin. SpTm is thought to stabilize matu...
The localisation of the determinants of the body axis during Drosophila oogenesis is dependent on the microtubule (MT) cytoskeleton. Mutations in the actin binding proteins Profilin, Cappuccino (Capu) and Spire result in premature streaming of the cytoplasm and a reorganisation of the oocyte MT network. As a consequence, the localisation of axis determinants is abolished in these mutants. It is...
