UniProtKB description: Mediates the transient calcium-dependent interaction of PYR/PYL/RCAR abscisic acid (ABA) receptors with the plasma membrane and thus regulates ABA sensitivity (By similarity). Stimulates the GTPase/ATPase activities of YCHF1, and regulates its subcellular localization (PubMed:19086295, PubMed:20876569, PubMed:23550829). Binds phospholipids in a Ca(2+)-independent manner (PubMed:20876569). Promotes tolerance towards salinity stress by limiting the accumulation of reactive oxygen species (ROS) (PubMed:19086295, PubMed:23550829). Promotes resistance to bacterial pathogens, such as Xanthomonas oryzae pv. oryzae and Pseudomonas syringae pv. tomato strain DC3000 (PubMed:19086295). Binding to YCHF1 is required for its role in stimulating defense responses and the ability to alleviate salt stress (PubMed:26286751).
