It binds two calcium ions (By similarity). Publication Abstract from PubMed Beta-parvalbumins from different fish species have been identified as the main elicitors of IgE-mediated reactions in fish-allergic individuals. Here, we report for the first time the NMR determination of the structure and dynamics of the major Atlantic cod (Gadus morhua) allergen Gad m 1 and compare them with other known parvalbumins. Although the Gad m 1 structure and accessibility of putative IgE epitopes are similar to parvalbumins in mackerel and carp, the charge distribution at the putative epitopes is different. The determination of the Gad m 1 structure contributes to a better understanding of cross-reactivity among fish parvalbumins. In addition, the high-pressure NMR and temperature variation experiments revealed the important contribution of the AB motif and other regions to the protein folding. This structural information could assist the future identification of hot spots for targeted mutations to develop hypoallergenic Ca(2+) -free forms for potential use in immunotherapy.
