InterPro domain: IPR007736

Caleosins are a family of lipid-associated proteins that are ubiquitous in plants and true fungi. In plants, caleosinss are Ca(2+)-binding oil-body surface proteins [ 1 ]. Later, caleosin was identified as a putative peroxygenase, which is involved in oxylipin metabolism during biotic and abiotic stress responses in Arabidopsis [ 2 ]. The calcium binding domain is probably related to the calcium-binding EF-hands motif IPR002048 .
