  (155/160 words):Mutations in acyl-CoA synthetase long-chain family member 4 (ACSL4),which converts long-chain fatty acids to acyl-CoAs,result in non-syndromic X-linked mental retardation.Using the Drosophila neuromuscular junction (NMJ) as a model,we found that dAcsl,the Drosophila homolog of ACSL4,inhibits synaptic growth by attenuating bone morphogenetic protein (BMP) signaling,a major growth-promoting pathway of NMJ synapses.
