摘要磷脂酰肌醇特异性磷脂酶 C (PLC) 是一个酶家族,在已知的最大类细胞信号传导途径之一中发挥着关键作用。哺乳动物PLC酶根据其结构特征和免疫学差异分为四大类和多种亚类。迄今为止,已经克隆了五种无脊椎动物 PLC 编码基因,这些基因属于哺乳动物 PLC 分类所用的四个主要类别中的三个类别。其中四个无脊椎动物基因是从果蝇中克隆出来的,一个是从卤虫(一种丰年虾)中克隆出来的。无脊椎动物酶的结构特征包括在主要类型的哺乳动物 PLC 中发现的高度保守的 Box X 和 Box Y 结构域的存在以及新特征。无脊椎动物 PLC 基因中的两个编码多种剪接变异亚型,这是在哺乳动物酶中观察到的新出现的多样性水平。无脊椎动物 PLC 的研究有助于识别单个同工酶的生理功能。这些已确定的作用包括光转导、嗅觉、细胞生长和分化等细胞过程。
abstractPhosphatidylinositol-specific phospholipase C (PLC) is a family of enzymes that occupy a pivotal role in one of the largest classes of cellular signaling pathways known. Mammalian PLC enzymes have been divided into four major classes and a variety of subclasses based on their structural characteristics and immunological differences. There have been five invertebrate PLC-encoding genes cloned thus far and these fall within three of the four major classes used in categorizing mammalian PLC. Four of these invertebrate genes have been cloned fromDrosophila melanogaster and one is fromArtemia, a brine shrimp. Structural characteristics of the invertebrate enzymes include the presence of highly conserved Box X and Box Y domains found in major types of mammalian PLC as well as novel features. Two of the invertebrate PLC genes encode multiple splice-variant subtypes which is a newly emerging level of diversity observed in mammalian enzymes. Studies of the invertebrate PLCs have contributed to the identification of the physiological functions of individual isozymes. These identified roles include cellular processes such as phototransduction, olfaction, cell growth and differentiation.
