Anti-CUL2 Cullin-2

0.5mg/ml if reconstituted with 0.2ml sterile DI water. Cullin-2 is a protein that in humans is encoded by the CUL2 gene. Using immunofluorescence, it was shown that CUL2 is a cytosolic protein that can be translocated to the nucleus by VHL. By fluorescence in situ hybridization, Clifford et al.(1999) mapped the gene to 10p11.2-p11.1, a region reported to show loss of heterozygosity (LOH) in several forms of human cancer, including non-clear cell renal cell carcinoma. Pause et al.(1997) suggested that CUL2 is a candidate tumor suppressor gene, as has been proposed for CUL1 (603134). Lonergan et al.(1998) demonstrated that formation of the VBC-CUL2 complexes is linked to the regulation of hypoxia-inducible mRNAs by VHL. CUL2 is one of several proteins required for degradation of a class of RNA-binding germline proteins in somatic cells of the early blastomere. Protein function: Core component of multiple cullin-RING-based ECS (ElonginB/C-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complexes, which mediate the ubiquitination of target proteins. May serve as a rigid scaffold in the complex and may contribute to catalysis through positioning of the substrate and the ubiquitin- conjugating enzyme. The E3 ubiquitin-protein ligase activity of the complex is dependent on the neddylation of the cullin subunit and is inhibited by the association of the deneddylated cullin subunit with TIP120A/CAND1. The functional specificity of the ECS complex depends on the substrate recognition component. ECS(VHL) mediates the ubiquitination of hypoxia-inducible factor (HIF). [The UniProt Consortium]
