ACBP — Brassica napus

Summary

BnACBP (DARMORV10_C02P18290.1) on chromosome C02 of oilseed rape encodes an acyl-CoA-binding protein containing ankyrin repeats and a FERM/acyl-CoA-binding domain. The product exhibits fatty-acyl-CoA binding, phospholipase D activity, glycerophospholipase activity, lipid binding, phosphatidate binding, and ubiquitin-protein transferase activity. It is associated with lipid transport, fatty acid homeostasis, sterol homeostasis, regulation of lipogenesis, triglyceride anabolism, seed maturation, seed dormancy, seedling development, leaf shaping, and response to lead ion. The gene has been linked to seed oil content, seed quality, protein content, leaf chlorosis, seed longevity, salt and drought tolerance, freezing tolerance, hypoxia tolerance, stomatal closure, cuticular wax accumulation, and resistance to Botrytis cinerea. It localises to the endoplasmic reticulum, plastid, mitochondria, plasmodesmata, and clathrin-coated vesicles. Studies of related genes in other species connect the family to oxidative stress tolerance, lead tolerance, pathogen resistance, leaf senescence, and embryogenesis.
