Immunofluorescence analysis of CUL-3 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with CUL-3 Rabbit Polyclonal Antibody (342200) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (A27034) a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing nuclear localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

Cullin 3 is a member of the family of human cullin genes (CUL 1, 2, 3, 4a, 4b, and 5) homologous to the S. cerevisiae cdc 53 gene. CUL 1 forms a complex with human p19 skp1 and F box protein p45 skp2. Together with cdc 53 (Known as Cul A), as three subunits, they form a ubiquitin ligase-controlling proteolysis of G1 cell cycle regulatory proteins. In contrast to CUL 1, CUL 2 does not associate with p19 skp1 and p45 skp2. 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.
