Binds nucleotic acids in vitro. Interacts with MPC. A number of isoforms are produced. According to EST sequences. Expressed in roots, leaves, stems, flowers and siliques. Detected in flowers only in growing organs: gynoecium, petals, stamenal filaments, anther walls and ovules. Expressed during early-embryogenesis in the embryo proper and the suspensor up to late heart stage. Expression is not detected in the embryo during maturation. Contains a PAM2-like motif, which seems to be involved in the binding to the PABC/CTC domain of PAB proteins.
