摘要
神经元轴突形成分支以与它们的目标建立精确的连接,但分支控制尚不清楚。Colavita和Tessier-Lavigne已经在秀丽隐杆线虫中发现了一个神经元子集,它需要一种叫做BAM-2(分支异常)的膜蛋白来阻止分支的形成并稳定它们的终止。bam2的缺失使得分支超过了它们正常的终止位点。bam2的序列与被认为控制神经元突触稳定性的神经素相似。A. Colavita, M. Tessier-Lavigne,神经素相关蛋白bam2在线虫轴突分支终止中的作用。科学302,293(2003)。【摘要】【全文】
Neuronal axons form branches to establish precise connections with their targets, but branch control is not well understood. Colavita and Tessier-Lavigne have identified a subset of neurons in Caenorhabditis elegans that require a membrane protein called BAM-2 (branching abnormal) to stop formation of branches and to stabilize their termination. Loss of BAM-2 allowed branches to overshoot their normal termination sites. BAM-2 shows sequence similarity to neurexins that are thought to control the stability of neuronal synapses. A.
