DESCRIPTION
Also known as CR15A_ARATH, COR15A. Exhibits cryoprotective activity toward stromal substrates (e.g. LDH and rubisco) in chloroplasts and in protoplasts and confers freezing tolerance to plants in a CBF-dependent manner (PubMed:1567390, PubMed:11038526, PubMed:9826741, PubMed:17384167, PubMed:18540080, PubMed:19563440). Protectant against various stresses (e.g. cold, drought and heat stress) by preventing protein aggregation (e.g. LDH) and attenuating enzyme inactivation (PubMed:18540080). Influences the intrinsic curvature of the inner membrane of the chloroplast envelope, and modulates the freeze-induced lamellar-to-hexagonal II phase transitions that occur in regions where the plasma membrane is brought into close apposition with the chloroplast envelope during freeze-induced osmotic contraction (PubMed:9826741). Mediates a shift in the melting curves of phospholipids-containing membranes to lower temperatures (PubMed:20510170). Involved in the regulation of leaf senescence by abscisic acid (ABA) in a VNI2-dependent manner (PubMed:21673078). Forms homooligomers which interact with potential stromal substrates in the stroma of chloroplasts (PubMed:17384167). Interacts with the galactose headgroup of the chloroplast lipid monogalactosyldiacylglycerol (MGDG) (PubMed:20510170).
