Active Recombinant Human CUL1/RBX1

• Cat.No.: CUL1-146H
• Product Overview: Recombinant human CUL1 (amino acid residues 1-776), RBX1 (amino acid residues 1-115) was expressed in Insect (Sf21) cells.

Specification

• Description: Cullin-RING-Ligases (CRLs) are one largest class of ubiquitin E3 ligases and the enzymes of the NEDDylation pathway play a pivotal role in the activation of these, akin to ubiquitylation, the E1 activating enzyme (APP-BP1/UBA3 heterodimer) and the E2 conjugating enzymes (UBE2M or UBE2F) are involved in mammalian NEDDylation of the Cullin Ring Ligases (CRLs) (Meyer-Schaller et al., 2009; Huang et al., 2011; Morimoto et al., 2003).
• Source: Insect cells
• Species: Human
• Form: 50 mM HEPES pH 7.5, 150 mM sodium chloride, 2 mM dithiothreitol, 10% glycerol.
• Bio-activity: E3 Ligase Assay: The activity of Cul1/Rbx1 was validated indirectly through its ability to act as a substrate for Neddylation in the presence of the NEDD8 E3 ligase His-DCNL2 and thioester-loaded His-Ube2M-NEDD8. Incubation of Cul1/Rbx1 and thioester loaded His-Ube2M-NEDD8 in the presence or absence of His-DCNL2 at 4?C was compared at two time points T0 and T2 minutes. Neddylation of the Cul1 subunit in the presence of His-DCNL2 was demonstrated.
