Description
Product Characteristics:
Cullin 2 is a member of the family of human Cullin genes (CUL1, 2, 3, 4a, 4b and 5) homologous to the S. cerevisiae cdc53 gene. It is a component of E3 ubiquitin ligase complexes, including the inactive transcriptional elongation complex SIII, which mediates the ubiquitination of hypoxia-inducible factor (HIF). SIII is formed by three subunits: Elongin C, Elongin B and VHL. Cullin 2 may serve as a rigid scaffold in the complex and may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme.
Subcellular location: Nucleus
Synonyms: Cullin2, Cullin-2, CUL 2, MGC131970, CUL2_HUMAN.
Target Information: 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)
