Description
UBE2F is an E2 conjugation enzyme that is involved in the ubiquitylation of target substrates, along with E1 and E3 enzymes. UBE2F mediates the transfer of NEDD8 from NEDD8-activating enzyme E1 (UBA3-NAE1 complex) to a substrate protein. This E2 enzyme has been shown to associate with the both NEDD8 E3 ligase and RBX2, yet displays different target cullin specificities than a similar UBE2M/RBX1 E2/E3 complex.
Life Sensors的泛素和泛素链泛素是一种小的多肽,通过其C端与目标蛋白上的赖氨酸的ε-氨基缀合。这种缀合称为单泛素化。随后,可以利用遍在蛋白表面上的七个赖氨酸残基(K6,K11,K27,K29,K33,K48,K63)中的任何一个,将额外的遍在蛋白部分与初始遍在蛋白结合。这种泛素链形成称为多泛素化。泛素的酶结合是通过一系列酶进行的,即泛素激活酶E1,泛素结合酶E2和泛素连接酶E3。蛋白质的泛素化在细胞中是可逆的。单泛素化和多泛素化的链均被去泛素化酶催化的水解作用裂解 (DUB)。LifeSensors在遍在泛素途径的所有水平的酶(包括E1,E2和E3酶和DUB)上都有丰富的经验。LifeSensors对蛋白质纯化的广泛了解使我们能够生产大约30种E2酶,20种E3酶和35个DUB,并具有定制表达的能力。此外,我们广泛的检测方法简化了确认酶活性和确定E2-E3对兼容性的过程,并确保您可以选择最能解决希望探索的特定,关键生物学问题的酶。LifeSensors已为您的研究开发了多种泛素衍生物,包括用于结合相互作用研究的DUB耐药性聚泛素链,用于DUB分析和筛选的泛素结合物(荧光团和报告酶),选择性泛素链(二,三和四环素)泛素链)用于DUB特异性和结合测定,位点特异性赖氨酸泛素突变体用于E3连接酶和DUB选择性测定。
