In Arabidopsis (Arabidopsis thaliana), a family of six genes encodes acyl-coenzyme A-binding proteins (ACBPs). A member of this family, ACBP1, contains an amino-terminal transmembrane domain that targets it to the plasma membrane and the endoplasmic reticulum. To investigate ACBP1 function, ...

Cytosolic 10-kDa acyl-CoA-binding proteins (ACBPs) function in the storage and intracellular transport of acyl-CoA esters in eukaryotes. Fatty acids synthesized de novo in plant chloroplasts are exported as oleoyl-CoA and palmitoyl-CoA esters. In Arabidopsis, other than the 10-kDa ACBP, there exists five larger ACBPs ...

� Acyl-CoA-binding proteins (ACBPs) show conservation in an acyl-CoA-binding domain (ACB domain) which binds acyl-CoA esters. Previous studies on plant ACBPs focused on eudicots, Arabidopsis and Brassica. Here, we report on the phylogeny and characterization of the ACBP family from the monocot Oryza sativa (rice). � Phylogenetic ...
ACBP3 is one of six Arabidopsis (Arabidopsis thaliana) genes, designated ACBP1 to ACBP6, that encode acyl-coenzyme A (CoA)-binding proteins (ACBPs). These ACBPs bind long-chain acyl-CoA esters and phospholipids and are involved in diverse cellular functions, including ...
Small 10-kD acyl-coenzyme A-binding proteins (ACBPs) are highly conserved proteins that are prevalent in eukaryotes. In Arabidopsis (Arabidopsis thaliana), other than the 10-kD ACBP homolog (designated Arabidopsis ACBP6), there are five larger forms of ACBPs ranging from 37.5 to 73.1 kD. In this study, the ...
Acyl-CoA esters have many intracellular functions, acting as energy source, substrate for metabolic processes and taking part in cell signaling. The acyl-CoA-binding protein (ACBP), a highly conserved 10 kDa intracellular protein, binds long- and medium-chain acyl-CoA esters with very high affinity, directing them to specific metabolic routes and protecting them from ...
The diazepam binding inhibitor (DBI) or the acyl-CoA-binding protein (ACBP) is a 9-10 kDa highly conserved multifunctional protein that plays important roles in GABA(A) receptor activity regulation, lipid absorption and steroidogenesis in various organisms. To study the functions of DBI/ACBP in insect development or diapause, we cloned the cDNA from ...
In our recent paper in Plant Physiology and Biochemistry, we reported that the mRNAs encoding Arabidopsis thaliana cytosolic acyl-CoA-binding proteins, ACBP4 and ACBP5, but not ACBP6, are modulated by light/dark cycling. The pattern of circadian-regulated expression in ACBP4 and ...
From opportunistic protist Cryptosporidium parvum we identified and functionally assayed a fatty acyl-CoA-binding protein (ACBP) gene. The CpACBP1 gene encodes a protein of 268 aa that is three times larger than typical ~10 KD ACBPs of humans and animals. Sequence analysis indicated that the ...

In Arabidopsis thaliana, a family of six genes (ACBP1 to ACBP6) encodes acyl-CoA binding proteins (ACBPs). Investigations on ACBP3 reported here show its upregulation upon dark treatment and in senescing rosettes. Transgenic Arabidopsis overexpressing ACBP3 ...
Cholesterol and fatty acyl-coenzymeA thioesters are signalling molecules with role in regulation of genes involved in lipid and glucose transport and metabolism. The studies described herein focused on three proteins that bind lipids and have different cellular functions: steroidogenic acute regulatory protein (StAR), hepatocyte nuclear factor-4a (HNF-4a) and acyl-CoA binding ...
Acyl-CoA-binding protein (ACBP) is a 10�kDa protein that binds C12�C22 acyl-CoA esters with high affinity. In vitro and in vivo experiments suggest that it is involved in multiple cellular tasks including modulation of fatty acid biosynthesis, enzyme regulation, regulation of the intracellular acyl-CoA pool size, donation of ...
Acyl-coenzyme A binding protein (ACBP) has been proposed to transport fatty acyl-CoAs intracellularly, facilitating their metabolism. In this study, a new mouse recombinant ACBP was produced by insertion of a histidine (his) tag at the C-terminus to allow efficient purification by Ni-affinity chromatography. The his-tag was inserted at the C-terminus since ...
ACBP (acyl-CoA-binding protein) is a small primarily cytosolic protein that binds acyl-CoA esters with high specificity and affinity. ACBP has been identified in all eukaryotic species, indicating that it performs a basal cellular function. However, differential tissue expression and the existence of several ACBP ...
Unique among the intracellular lipid binding proteins, acyl-CoA binding protein (ACBP) exclusively binds long-chain fatty acyl-CoAs (LCFA-CoAs). To test if ACBP is an essential protein in mammals, the ACBP gene was ablated by homologous recombination in mice. While ACBP heterozygotes appeared ...
ACBPs are implicated in acyl-CoA trafficking in many eukaryotes and some prokaryotes. Six genes encode proteins designated as AtACBP1-AtACBP6 in the Arabidopsis thaliana ACBP family. These ACBPs are conserved in the acyl-CoA-binding domain, but vary in size from 92 amino ...
Multiple classes of acyl-CoA binding proteins are encoded by plant genomes, including a plant-unique class of predicted integral membrane-proteins. Transcript analysis revealed that both of the integral membrane-acyl-CoA binding proteins of Arabidopsis thaliana, ACBP1 and ACBP2, are expressed in al...

The N-terminal amino-acid sequence of a major rice phloem-sap protein, named RPP10, was determined. RPP10 is encoded by a single gene in the rice genome. Its complete amino-acid sequence, predicted from the corresponding rice full-length cDNA, showed high similarity to plant acyl-CoA-binding proteins (ACBPs). Western blot analysis using ...
The acyl-CoA binding protein (ACBP) and the diazepam binding inhibitor (DBI) or endozepine are independent isolates of a single 86-amino-acid, 10-kDa protein. ACBP/DBI is highly conserved between species and has been identified in several diverse organisms, including human, cow, rat, frog, duck, insects, plants, and yeast. Although the genomic locus has ...

We have characterized binding activities in yeast which recognise the T-rich strand of the yeast ARS consensus element and have purified two of these to homogeneity. One (ACBP-60) is detectable in both nuclear and whole cell extracts, while the other (ACBP-67) is apparent only after fractionation of extracts by heparin-sepharose chromatography. The major ...
Fatty liver disease is a common lipid metabolism disorder influenced by the combination of individual genetic makeup, drug exposure, and life-style choices that are frequently associated with metabolic syndrome, which encompasses obesity, dyslipidemia, hypertension, hypertriglyceridemia, and insulin resistant diabetes. Common to obesity related dyslipidemia is the excessive storage of hepatic ...
