    Expressioni

    Tissue specificityi

    Highly expressed in developing endosperm and in roots and, at lower levels, in coleoptiles and aleurone. In 3 day old roots it is detected in cap cells and along the vascular strand, starting just after the meristemic region. In 9 day old leaves it is found in the phloem. In seeds it is distributed throughout the endosperm and also found in the assimilate-unloading tissues, the nucellar projection, the vascular area and at a high concentration in the chalazal region.1 Publication

    Developmental stagei

    Activity increases as seeds develop.1 Publication

    Interactioni

    Subunit structurei

    Forms homotetramers. In endosperm it forms both homotetramers and heterotetramers with SS2, all three possible heterotetramers are formed.1 Publication
