RING-box protein 1 (RBX1 or ROC1) is an essential component of two distinct but structurally related E3 ubiquitin ligase complexes, the SCF complex and the CBC (VHL) complex (1). RBX1 mediates the neddylation of CUL1, which activates SCF E3 ligase by facilitating the ubiquitin transfer from E2 to substrates (2-4). The RING finger domain of RBX1 is required for ubiquitin ligation (5). Two evolutionarily conserved mammalian RBX family members, RBX1/ROC1 and RBX2/ROC2/SAG, have been identified (5). RBX1 is constitutively expressed and binds to CUL2/VHL, while stress-inducible RBX2 binds to CUL5/SOCS (6).

RING-box protein 1 (RBX1 or ROC1)是两种不同但是结构上相关的E3泛素连接酶复合物SCF复合物以及CBC (VHL)中的一个必需的组分(1)。RBX1能够介导CUL1的neddylation,这可以促进泛素从E2转移到底物从而活化SCF E3连接酶(2-4)。RBX1的RING finger结构域是泛素连接所需要的(5)。两种进化上保守的哺乳动物RBX家族成员,RBX1/ROC1 和 RBX2/ROC2/SAG,已经被鉴定出来(5)。RBX1是组成型表达,能够与CUL2/VHL结合,而RBX2是应激诱导型,能够与CUL5/SOCS结合 (6)。
