ACBP2 Antibody specifically binds to ACBP2, a member of the acyl-CoA-binding protein family that facilitates intracellular transport of acyl-CoA esters and regulates lipid metabolism. ACBP2 is distinct from other isoforms (e.g., ACBP1, ACBP/DBI) due to its unique expression patterns and functional roles .
In Arabidopsis thaliana, ACBP2-specific antibodies revealed its expression in developing embryos, where it collaborates with ACBP1 to mediate lipid transfer during early embryogenesis. Key findings include:
Embryo Lethality: Double mutants (acbp1acbp2) failed to develop viable embryos, underscoring ACBP2's necessity in lipid mobilization for seed development .
Lipid Profiling: Siliques of acbp2 mutants showed reduced polyunsaturated phospholipids (e.g., phosphatidylcholine) and accumulation of galactolipids, indicating disrupted lipid homeostasis .
In Toxoplasma gondii, ACBP2 antibodies were used to validate mitochondrial localization and roles in cardiolipin metabolism:
Mitochondrial Dysfunction: ACBP2-deficient parasites exhibited impaired growth, disrupted cardiolipin synthesis, and apoptosis-like death under stress .
Virulence Attenuation: ACBP2 knockout reduced virulence in mice, linking lipid metabolism to pathogenicity .
ACBP2 Antibody has been employed in diverse experimental techniques:
Essential Role in Embryogenesis: ACBP2 is indispensable for lipid transfer during early seed development in plants .
Mitochondrial Lipid Metabolism: In Toxoplasma, ACBP2 maintains cardiolipin levels critical for mitochondrial integrity and virulence .
Therapeutic Potential: Targeting ACBP2 in pathogens like Toxoplasma could inform antiparasitic strategies .
