title: Pt2L4 protein, a homologue to Hev b 5 from rubber tree, may not be responsible for the cross-reactions to cassava show by people allergic to latex.
abstract: Pt2L4 is a protein from cassava homologue to Hevb5, a principal allergen from latex. Here we aimed to elucidate immunological relationships between these proteins. Our results revealed that epitopes found in Hev b 5 are not entirely conserved in Pt2L4 which is not recognized by IgE from patients allergic to Hev b 5.
