Cardosin A is an RGD-containing aspartic proteinase from the stigmatic papillae ofCynara cardunculusL. A putative cardosin A-binding protein has previously been isolated from pollen suggesting its potential involve-ment in pollen–pistil interaction [Faro C, Ramalho-Santos M, Vieira M, Mendes A, Simo˜es I, Andrade R, Verissimo P, Lin X, Tang J & Pires E (1999) J Biol Chem274, 28724–28729]. | iFEBS Journal Molecular analysis of the interaction between cardosin A and phospholipase Da Identification of RGD KGE sequences as binding motifs for C2 domains Isaura Simoes1 Eva-Christina Mueller2 Albrecht Otto2 Daniel Bur3 Alice Y.

Here we report the identification of phospholipase Da as a cardosin A-binding protein. The interaction was confirmed by coimmunoprecipitation studies and pull-down assays. To investigate the structural and molecular determinants involved in the interaction pull-down assays with cardosin A and various glutathione S-trans-ferase-fused phospholipase Da constructs were performed. Results revealed that the C2 domain .
