Expressed in the radicle of germinating seeds 2 days post-imbibition (DPI) and in roots of 30-DPI young plants. Expressed in the embryo and seed coat tissues of developing seeds. The protein accumulates only in seeds and only long after transcript accumulation becomes evident. Peak of expression in seeds between 3 and 28 days post-anthesis. The BURP domain located at the C-terminus has not been identified in non-plant proteins.
