| abstractText | X-linked adrenoleukodystrophy (X-ALD) is a neurodegenerative disorder characterized by demyelination of white matter. The X-ALD gene product adrenoleukodystrophy protein (ALDP) is expressed broadly among various tissues. However, deficiency of functional ALDP exclusively impairs brain, adrenal gland, and testis. Thus, loss of ALDP function is assumed to involve inactivation of a putative mediating factor that functions in a tissue-specific manner. Here we cloned a mouse cDNA encoding a novel protein, Lipidosin, that possesses long-chain acyl-CoA synthetase (LCAS) activity. Lipidosin is expressed exclusively in mouse brain, adrenal gland, and testis, which are affected by X-ALD. LCAS activity of Lipidosin was diminished by mutation of conserved amino acids within the AMP-binding domain. Mutation of the Drosophila homologue of Lipidosin has been reported to cause neuronal degeneration. Thus, Lipidosin may mediate the link between ALDP dysfunction and the impairment of fatty acid metabolism in X-ALD. |
