Corn pollen protein (CPP)

Corn pollen protein refers collectively to the diverse set of proteins present within maize (Zea mays) pollen. This group includes several well-characterized allergens—notably those designated by names such as Zea m 1 (expansin B family), Zea m 13, among others—which can trigger IgE-mediated allergic responses in susceptible individuals due to cross-reactivity with other grass pollens[2][3][6]. The major functional classes represented include enzymes involved in cell wall modification during fertilization processes—such as endoxylanases and beta-glucanases that facilitate penetration through stigma tissues—and structural/modulatory molecules like expansins that loosen plant cell walls during germination/pollination events [1][2]. Additionally, some corn pollen-derived peptide hydrolysates have demonstrated antioxidant and antimicrobial activities with potential nutraceutical applications [7]. However, because "corn pollen protein" is an umbrella term covering many different molecules rather than one defined target or receptor, it should not be treated as a single canonical therapeutic target.
