In flowers, expressed in anthers, pollen and developing ovules (PubMed:17293437). In inflorescences, accumulates mainly in mature pistils (PubMed:27524487). In developing ovules, observed at the micropylar region in a polarized localization of the synergid cells and in inner integument surrounding the female gametophytes (at protein level) (PubMed:27524487). In mature ovules, present in the filiform apparatus and in the integuments at the micropylar region (PubMed:27524487). At later developmental stages, localization shifts from the micropyle toward the chalazal end (PubMed:27524487). Also present in the funiculus and at the junctions between the transmitting tissue and the funiculus (PubMed:27524487). Levels fade out in ovules after pollination and subsequent fertilization (PubMed:27524487).
May act as a carbohydrate transporter (PubMed:24470637). Required, together with ENODL11, ENODL12, ENODL13, ENODL14 and ENODL15, for male-female communication and pollen tube reception and burst at the synergid cell surface of the female gametophyte (PubMed:27524487).
