CES1(羧酸酯酶1)是一种重要的水解酶,属于羧酸酯酶基因家族(CES家族),该家族成员广泛存在于哺乳动物中,主要参与酯类、酰胺类和硫酯类化合物的代谢。CES1在人体中主要由肝脏表达,也在巨噬细胞、脂肪组织和肠道等部位有分布。它的主要功能是催化多种内源性和外源性物质的代谢,包括药物(如抗病毒药物奥司他韦、抗血小板药物氯吡格雷)、环境毒素和内源性脂质(如胆固醇酯和甘油三酯)。CES1通过水解这些底物,帮助机体解毒和维持脂质稳态。CES1的突变可能导致酶活性改变,进而影响药物代谢效率,例如某些突变会降低奥司他韦的活化,导致药效减弱。此外,CES1功能异常还与代谢性疾病(如肥胖、糖尿病和脂肪肝)相关,因为它参与脂质代谢调控。如果CES1过表达,可能增强某些药物的代谢速率,导致药效降低,同时也可能影响脂质分解,加剧高脂血症或脂肪堆积。相反,CES1表达降低可能导致药物蓄积中毒,并可能因脂质代谢障碍引发代谢综合征。CES1基因家族成员(如CES2、CES3)具有相似的水解酶活性,但底物偏好和组织分布不同,例如CES2更倾向于水解含有较小醇基的酯类。总的来说,CES1在药物代谢和脂质调控中起关键作用,其表达水平或活性变化可能对健康和疾病治疗产生重要影响。
This gene encodes a member of the carboxylesterase large family. The family members are responsible for the hydrolysis or transesterification of various xenobiotics, such as cocaine and heroin, and endogenous substrates with ester, thioester, or amide bonds. They may participate in fatty acyl and cholesterol ester metabolism, and may play a role in the blood-brain barrier system. This enzyme is the major liver enzyme and functions in liver drug clearance. Mutations of this gene cause carboxylesterase 1 deficiency. Three transcript variants encoding three different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]
