May form complexes with phosphorylated ligands by interfering with kinases and their effectors (By similarity). Regulates seed germination via the abscisic acid (ABA) and gibberellic acid (GA)signaling pathways. During seed germination, MFT expression is directly repressed by ABI3 or promoted by ABI5 in the ABA signaling pathway. Involved in a negative feedback regulation of ABA signaling. Promotes embryo growth by direct repression of ABI5. In the GA signaling pathway, MFT expression is promoted by the DELLA protein RGL2 during seed germination (PubMed:20551347). May regulate seed germination and fertility through the brassinosteroid (BR) signaling pathway (PubMed:20935478). Expressed in gametophytes and developing seeds. By abscisic acid. No visible phenotype under normal growth conditions, but mutant seeds show hypersensitivity to ABA during seed germination. Belongs to the phosphatidylethanolamine-binding protein family.
