蛋白水解酶激活受体(PARs)是一类独特的G蛋白偶联受体(GPCRs)家族,在其胞外N末端被蛋白水解性裂解后被不可逆转地激活。PARs在止血、血栓形成、炎症、胚胎发育和癌症进展中发挥关键作用。由于PAR激活的不可逆蛋白水解性,受体的信号传递受到严格的调控。三个不同的过程,包括脱敏、内化和溶酶体降解,调节激活的PAR信号的时间和空间方面。翻译后修饰在调控这些过程中起着至关重要的作用,我们在这里综述了PAR翻译后修饰的性质及其在信号调节中的重要性。PARs被许多蛋白水解酶激活,其中一些可以引起不同的细胞反应,但这种有偏见的激动剂是如何确定的尚不清楚。进一步研究PARs翻译后修饰的功能将有助于更好地理解诱导性激动剂的生理调节以及PAR信号如何在不同的细胞环境中受到精确控制。
Protease-activated receptors (PARs) are a unique family of G protein-coupled receptors (GPCRs) that are irreversibly activated following proteolytic cleavage of their extracellular N-terminus. PARs play critical functions in hemostasis, thrombosis, inflammation, embryonic development and cancer progression. Due to the irreversible proteolytic nature of PAR activation, signaling by the receptors is tightly regulated. Three distinct processes including desensitization, internalization and lysosomal degradation, regulate the temporal and spatial aspects of activated PAR signaling. Posttranslational modifications play a critical role in regulating each of these processes and here we review the nature of PAR posttranslational modifications and their importance in signal regulation. The PARs are activated by numerous proteases, and some can elicit distinct cellular responses, how this biased agonism is determined is unknown. Further study of the function of posttranslational modifications of the PARs will lead to a greater understanding of the physiological regulation of baised agonism and how PAR signaling is precisely controlled in different cellular contexts.
