Functioni

Together with GPA1, may regulate the cell cycle via a signaling cascade that uses phosphatidylinositol-specific phospholipase C (PI-PLC) as an effector and inositol 1,4,5-trisphosphate(IP3) as a second messenger. Acts as a negative regulator of GPA1-mediated abscisic acid (ABA) responses in guard cells, and together with GPA1 and GB1 during seed germination and early seedling development. Promotes PI-PLC activity and IP3 accumulation. Involved in the blue light (BL) signaling. Together with GPA1 and ADT3, required for BL-mediated synthesis of phenylpyruvate and subsequently of phenylalanine (Phe), in etiolated seedlings. Probably involved in cytokinin signal transduction. Plays a positive role in gibberellin- (GA) and brassinosteroid- (BR) regulated seed germination, probably independently of a heterotrimeric G-protein. Mediates seed dormancy abolition, and promotes seed germination and flowering.8 Publications

Disruption phenotypei

Hypersensitivity to abscisic acid (ABA) and to the lipid metabolite, sphingosine-1-phosphate (S1P), a transducer of the ABA signal. Improved drought tolerance accompanied by lower rates of water loss. Impaired sensitivity to gibberellin (GA) and brassinosteroid (BR) in seed germination. Hypersensitivity to ABA and glucose (Glc) during and after seed germination. Altered response to blue light (BL).5 Publications

Developmental stagei

In seedlings, mostly expressed in small roots, and to a lower extent in hypocotyls. In young plants, equaly expressed in leaves, roots, and shoot tip. In old plants, present in roots, flower buds and young siliques, but not in leaves.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
