General description

Cullin 3 is a member of the cullin family of E3 ubiquitin protein ligases. Cullin 3 forms the BTB-Cul3-Rbx1 (BCR) ubiquitin ligase complex that contains a RING-box protein, Rbx1, and a BTB containing protein. Rbx1 binds to the C-terminus of cullin 3 through its RING-type zinc finger domain to recruit a ubiquitin-conjugating enzyme. The BTB containing protein binds cullin 3 at its N-terminus and functions as a cullin specific adaptor protein.

Application

Anti-Cullin 3 antibody produced in rabbit has been used in
  • western blotting
  • immunoprecipitation
  • immunofluorescence

Biochem/physiol Actions

Cullin 3 (Cul3) acts as a key mediator of post-translational protein regulation. It functions as a scaffold protein that assemble multi-subunit ubiquitin ligase complexes which are responsible for the specific recognition and targeting of substrates for ubiquitin-dependent degradation by the 26S proteasome. Cul3 is required for degradation of the microtubule-severing protein MEI-1/katanin during transitioning from meiosis-to-mitosis phase. It forms a catalytically inactive BTB-Cul3-Rbx1 (BCR) ubiquitin ligase and becomes functional upon covalent attachment of the ubiquitin homologue neural-precursor-cell-expressed. BCR ubiquitin ligase down regulated 8 (Nedd8) near the C terminus of Cul3.

Many biological processes, such as development and cell cycle progression are tightly controlled by selective ubiquitin-dependent degradation of key substrates. In this pathway, the E3-ligase recognizes the substrate and targets it for degradation by the 26S proteasome. The SCF (Skp1-Cul1-F-box)

Cullin-RING complexes comprise the largest known class of ubiquitin ligases. Owing to the great diversity of their substrate-receptor subunits, it is possible that there are hundreds of distinct cullin-RING ubiquitin ligases in eukaryotic cells, which establishes these enzymes as key

Cyclin E is an unstable protein that is degraded in a ubiquitin- and proteasome- dependent pathway. Two factors stimulate cyclin E ubiquitination in vivo: when it is free of its CDK partner, and when it is phosphorylated on threonine 380.

Cullin-based E3 ligases target substrates for ubiquitin-dependent degradation by the 26S proteasome. The SCF (Skp1-Cul1-F-box) and ECS (ElonginC-Cul2-SOCS box) complexes are so far the best-characterized cullin-based ligases. Their atomic structure has been solved recently, and several substrates have been described
