Description Proctolin is a bioactive neuropeptide that modulates interneuronal and neuromuscular synaptic transmission in a wide variety of arthropods.
In vitro Proctolin是一种广泛分布于节肢动物中的昆虫神经肽。它能够增加动作电位的频率、增强肌肉收缩的幅度,并在静息系统中引发活动[1]。在节肢动物中,Proctolin作为神经调节剂,可能也作为神经激素发挥作用,但似乎不作为传统的神经递质[2]。Proctolin是一个由RYLPT成熟肽段组成的五肽,是第一个被序列化和化学特征化的昆虫神经肽。D. melanogaster中Proctolin前体基因的首次鉴定为CG7105。尽管早期研究显示B. mori中不存在Proctolin,但最近在B. mori翅膀的蛋白质组分析中鉴定出了这种五肽。然而,Bombyx的Proctolin基因因为在RYLPT序列的N-端和C-端缺乏切割位点,未能产生成熟的肽段,C. suppressalis中观察到了类似的基因。因此,认为在B. mori和C. suppressalis中并未真正观察到Proctolin[3]。
