Localization

Localization Comment Organism GeneOntology No. Textmining
plasma membrane actinidin is present in small cells, but not large cells in the outer pericarp of mature Actinidia deliciosa fruit at harvest. Within the small cells, actinidin is localised diffusely in the vacuole, associated with the plasma membrane, and in a layer in the plastids near starch granules Actinidia deliciosa 5886

fruit actinidin mRNAs for acidic and basic proteins are expressed at comparable levels throughout ripening. Actinidin mRNA expression is highest in fruit at harvest, expression decreases as fruit ripened and is much lower in the core compared with outer pericarp tissue. Low levels of a basic actinidin protein (KFAct2a) in ripe Actinidia chinensis fruit. Extremely high levels of an acidic actinidin protein (KFAct1a) is detected in Actinidia chinensis EM4 fruit. This acidic protein appears to be absent in Actinidia chinensis Hort16A Actinidia chinensis
