Probable RNA-binding protein involved in the regulation of abscisic acid (ABA) response during seed germination. May regulate transcript levels of several germination-responsive genes under ABA. A number of isoforms are produced. According to EST sequences. Expressed in vasculature of leaves, roots and siliques. Down-regulated by abscisic acid (ABA). No visible phenotype under normal growth conditions, but mutant seeds have decreased germination rate in presence of abscisic acid (ABA) or salt, compared to wild-type. Sequencing errors.
