PRL and allergic disease: BlotAQP1, BlotAQP2, and BlotAQP5 were clustered with the aquaglyceroporins hAQP3, hAQP7, hAQP9, and hAQP10, with a common sequence consensus ‘N-G-NPSRD-PRL.’ The molecular weight and isoelectric point of these molecules were consistent with the findings reported by Maoet al. in their two-dimensional electrophoresis study.23 This observation suggests the potential recognition of aquaporins, specifically aquaglycerins such as AQP3, by IgE in patients with allergies.
