GPA1 (G-protein alpha-1) is a modulator or transducer for a variety of transmembrane signaling systems. Together with GCR1, it may regulate the cell cycle through a signaling cascade that promotes the cell-protecting abscisic acid (ABA) response. However, together with GCR1 and GB1, they act as negative regulators of ABA during seed germination and early seedling development. Participate in blue light (BL) signals. Alias :GP-alpha-1.
