As the largest family of integral membrane proteins,G-protein-coupled receptors(GPCRs) comprise the largest class of therapeutic targets that aimed by approximately 45 %of modern medicinal drugs.Therefore,understanding the signal transduction,as well as the agonist/antagonist mechanism of the GPCRs,is pivotal in drug discovery and new therapeutic strategy development.

在色谱、分子光谱等分析信号中,准确的峰检测对后续的分析非常重要。然而,重叠峰对主要峰参数的确定影响严重,增加了进一步数据分析的难度。在本文中,我们提出递归小波峰检测和解卷积方法(RWPD),该方法主要针对重叠峰进行峰检测、解卷积和主要峰参数的估计。
