CUL-2 is a member of the family of human cullin genes (CUL-1, -2, -3, -4a, -4b, and -5), homologous to the S. cerevisiae cdc53 gene. CUL-1 forms a complex with human p19skp1 and F box protein p45skp2. Together with cdc53 (known as CulA), the three subunits, form a ubiquitin ligase controlling proteolysis of G1 cell cycle regulatory proteins. In contrast to CUL-1, CUL-2 does not associate with p19skp1 and p45skp2. Instead, CUL-2 forms a complex with an inactive transcriptional elongation complex, SIII, formed by three subunits: Elongain C, Elongin B and VHL. The function of this association remains unknown.
