Anti-Cullin 2/CUL2 Antibody Picoband®

Cullin 2 (CUL2) is a protein that in humans is encoded by the CUL2 gene. Using immunofluorescence, they showed 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 CUL2 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 was one of several proteins required for degradation of a class of RNA-binding germline proteins in somatic cells of the early blastomere.

A synthetic peptide corresponding to a sequence in the middle region of human Cullin 2, different from the related mouse and rat sequences by one amino acid.

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 (By similarity) . The functional specificity of the ECS complex depends on the substrate recognition component. ECS (VHL) mediates the ubiquitination of hypoxia-inducible factor (HIF) . .
