ATP Binding Cassette Subfamily D Member 2 (ABCD2) Antibody

Background

ABCD2 is a peroxisomal ATP-binding cassette transporter that plays a key role in the import of very-long-chain fatty acids (VLCFAs) and their derivatives into peroxisomes for β-oxidation. It is highly expressed in tissues such as the liver, brain, and adrenal glands, where VLCFA metabolism is essential for cellular function and homeostasis. Structurally, ABCD2 contains nucleotide-binding domains that drive ATP-dependent substrate transport across the peroxisomal membrane. ABCD2 shares functional redundancy with ABCD1, compensating for its loss in certain conditions such as X-linked adrenoleukodystrophy (X-ALD). Dysregulation of ABCD2 expression has been associated with metabolic disorders involving lipid accumulation and peroxisomal dysfunction, highlighting its importance in lipid metabolism and cellular health.
