1、内皮素T/Endothelin-l(ETT),是人类内皮素的三种异构体之一内皮素-Endothelin-I(ET-I),也称为前内皮素-1(PPETl),是一种由血管内皮细胞产生的强效血管收缩肽。该基因编码的蛋白质EDNl经过蛋白水解处理,释放内皮素1。内皮素1是人类内皮素的三种异构体之一。内皮素前体是肽ET-I的前体。内皮细胞将内皮素原转化为内皮素原,随后转化为成熟的内皮素,细胞释放内皮素。Aliases:EDNl,ARCND3,ETl,HDLCQ7zQME,endothelin1,PPETlEndothelin(ET)-Iisapotentvasoconstrictorpeptideori
