四种钙信号蛋白及其在寄生虫学上的初步研究

不同种类的寄生虫入侵宿主和入侵后在宿主体内生存的机制非常复杂,但是影响这两个过程的主要因素目前已逐渐被揭示.Ca2+是寄生虫体内的一种重要的金属离子,它影响着寄生虫的许多生理生化活动,如运动、信号转导、渗透压的维持等.而Ca2+信号蛋白则是Ca2+能够发挥重要作用的直接承担者,钙离子信号蛋白是直接可以与Ca2+结合的蛋白质,它被Ca2+激活以后又可以与下游和他具有相互作用的蛋白质结合,从而使寄生虫发挥相应的生理生化作用.对能够与Ca2+信号蛋白结合的蛋白进行研究,有助于研制抗寄生虫的新药物和生物制剂,因为它们可能是一种存在于寄生虫体内潜在的新药物受体和靶标,而只有Ca2+信号蛋白被Ca2+活化以后才可以对这一互作蛋白展开深入的研究.本文综述了在寄生虫体内存在的4种Ca2+信号蛋白的重要性质和作用机制,对开展寄生虫Ca2+信号蛋白及其下游的互作蛋白的研究提供了一个比较基础的材料.
FOUR CALCIUM SIGNALING PROTEINS AND THEIR PRELIMINARY STUDIES IN PARASITOLOGY
The invasion of a variety of parasites to hosts and their survival mechanisms in hosts are extremely complicated.However,the main elements that have an impact on these two processes have been revealed gradually.Calcium ion is a kind of important metal ions in parasites and influences a lot of physiological and biochemical activities,such as sports,signal transduction and osmotic pressure maintenance.Calcium ion signaling protein plays a key role by directly binding with calcium ion and interacting with other proteins on the downstream.As a result,a series of physiological and biochemical effects occur in parasites.Because the interaction proteins with calcium ion signaling protein may be the potential new drug receptors and targets,the research of the interaction proteins with calcium ion signaling protein will be of help to develop new drugs and biologics against parasites.However,we cannot further investigate the interaction proteins with calcium ion signaling protein until calcium ion activates calcium ion signaling protein.This paper reviews the important properties and action mechanisms of four calcium ion signaling proteins that exist in parasites and will provide useful information on future studies.
