General Information

General Information Comment Organism
malfunction dAcsl mutants exhibit neuromuscular junction (NMJ) overgrowth that is suppressed by reducing the doses of the bone morphogenetic protein, BMP, pathway components, accompanied by increased levels of activated BMP receptor Thickveins (Tkv) and phosphorylated mothers against decapentaplegic (Mad), the effector of the BMP signaling at NMJ terminals. In addition, Rab11, a small GTPase involved in endosomal recycling, is mislocalized in dAcsl mutant NMJs, and the membrane association of Rab11 is reduced in dAcsl mutant brains. The staining pattern of Rab11 is markedly alteredin dAcsl mutant NMJs, the abnormal Rab11 localization is specifically caused by dAcsl mutations. Consistently, the BMP receptor Tkv accumulates in early endosomes but is reduced in recycling endosomes in dAcsl mutant NMJs. The level of activated BMP receptor Tkv is elevated in dAcsl mutants. Phenotype, overview. The extended presynaptic distribution of Rab11 is completely reversed by both presynaptic and ubiquitous expression of human ACSL4 Drosophila melanogaster
malfunction insights into the pathogenesis of ACSL4-related mental retardation, overview Homo sapiens
physiological function ACSL4 regulates neural development, role of ACSL4 in endosomal trafficking in vivo. ACSL4 is highly expressed in the hippocampus, a structure critical for learning and memory. Recombinant expression of human ACSL4 rescues the endocytic trafficking and neuromuscular junction (NMJ) phenotypes of Drosophila melanogaster enzyme mutants of the homologue dAcsl. The extended presynaptic distribution of Rab11 is completely reversed by both presynaptic and ubiquitous expression of human ACSL4 Homo sapiens
physiological function dAcsl, the Drosophila orthologue of ACSL4 and ACSL3, inhibits synaptic growth by attenuating bone morphogenetic protein, BMP, signaling, a major growth-promoting pathway at neuromuscular junction (NMJ) synapses. dAcsl is also required for the recycling of photoreceptor rhodopsin in the eyes, implying a general role for dAcsl in regulating endocytic recycling of membrane receptors, dAcsl promotes rhodopsin recycling in photoreceptors, dAcsl inhibits endocytosis of BMP receptors. dAcsl regulates the membrane distribution of Rab11 at NMJs. dAcsl genetically interacts with rab11 in attenuating BMP signaling at NMJ synapses through facilitating Rab11 dependent BMP receptor recycling Drosophila melanogaster
