ID:CUL1_HUMAN DESCRIPTION: RecName: Full=Cullin-1; Short=CUL-1; FUNCTION: Core component of multiple cullin-RING-based SCF (SKP1- CUL1-F-box protein) E3 ubiquitin-protein ligase complexes, which mediate the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription. In the SCF complex, serves as a rigid scaffold that organizes the SKP1-F-box protein and RBX1 subunits. 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. The functional specificity of the SCF complex depends on the F-box protein as substrate recognition component. SCF(BTRC) and SCF(FBXW11) direct ubiquitination of CTNNB1 and participate in Wnt signaling. SCF(FBXW11) directs ubiquitination of phosphorylated NFKBIA. SCF(BTRC) directs ubiquitination of NFKBIB, NFKBIE, ATF4, SMAD3, SMAD4, CDC25A, FBXO5 and probably NFKB2. SCF(SKP2) directs ubiquitination of phosphorylated CDKN1B/p27kip and is involved in regulation of G1/S transition. SCF(SKP2) directs ubiquitination of ORC1, CDT1, RBL2, ELF4, CDKN1A, RAG2, FOXO1A, and probably MYC and TAL1. SCF(FBXW7) directs ubiquitination of cyclin E, NOTCH1 released notch intracellular domain (NICD), and probably PSEN1. SCF(FBXW2) directs ubiquitination of GCM1. SCF(FBXO32) directs ubiquitination of MYOD1. SCF(FBXO7) directs ubiquitination of BIRC2 and DLGAP5. SCF(FBXO33) directs ubiquitination of YBX1. SCF(FBXO11) does not seem to direct ubiquitination of TP53. SCF(BTRC) mediates the ubiquitination of NFKBIA at 'Lys-21' and 'Lys-22'; the degradation frees the associated NFKB1-RELA dimer to translocate into the nucleus and to activate transcription. SCF(Cyclin F) directs ubiquitination of CP110 (By similarity). PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Component of multiple SCF (SKP1-CUL1-F-box) E3 ubiquitin- protein ligase complexes formed of CUL1, SKP1, RBX1 and a variable F-box domain-containing protein as substrate-specific subunit. Component of the SCF(FBXW11) complex containing FBXW11. Component of the SCF(SKP2) complex containing SKP2, in which it interacts directly with SKP1, SKP2 and RBX1. Component of the SCF(FBXW2) complex containing FBXw2. Component of the SCF(FBXO32) complex containing FBXO32. Component of the probable SCF(FBXO7) complex containing FBXO7. Component of the SCF(FBXO11) complex containing FBXO11. Component of the SCF(FBXO25) complex containing FBXO25. Component of the SCF(FBXO33) complex containing FBXO33. Component of the probable SCF(FBXO4) complex containing FBXO4. Component of the SCF(FBXO44) complex, composed of SKP1, CUL1 and FBXO44. Interacts with RNF7. Part of a complex with TIP120A/CAND1 and RBX1. The unneddylated form interacts with TIP120A/CAND1 and the interaction negatively regulates the association with SKP1 in the SCF complex. Interacts with COPS2. Can self-associate. Interacts with FBXW8. Interacts with CUL7; the interaction seems to be mediated by FBXW8. Component of the SCF(BTRC) complex, composed of SKP1, CUL1 and BTRC. This complex binds phosphorylated NFKBIA. Part of a SCF complex consisting of CUL1, RBX1, SKP1 and FBXO2 (By similarity). Component of a SCF(SKP2)-like complex containing CUL1, SKP1, TRIM21 and SKP2. Interacts with TRIM21. Interacts with Epstein-Barr virus BPLF1. Component of the SCF(FBXO17) complex, composed of SKP1, CUL1 and FBXO17. Component of the SCF(FBXO27) complex, composed of SKP1, CUL1 and FBXO27. Component of the SCF(Cyclin F) complex consisting of CUL1, RBX1, SKP1 and CCNF. Interacts with human adenovirus early E1A protein; this interaction inhibits RBX1-CUL1-dependent elongation reaction of ubiquitin chains by the SCF(FBW7) complex. Interacts with CHEK2; mediates CHEK2 ubiquitination and regulates its function. INTERACTION: Q86VP6:CAND1; NbExp=18; IntAct=EBI-359390, EBI-456077; P49427:CDC34; NbExp=3; IntAct=EBI-359390, EBI-975634; Q00987:MDM2; NbExp=3; IntAct=EBI-359390, EBI-389668; P62877:RBX1; NbExp=12; IntAct=EBI-359390, EBI-398523; P63208:SKP1; NbExp=6; IntAct=EBI-359390, EBI-307486; Q13309:SKP2; NbExp=8; IntAct=EBI-359390, EBI-456291; TISSUE SPECIFICITY: Expressed in lung fibroblasts. PTM: Neddylated; which enhances the ubiquitination activity of SCF. Deneddylated via its interaction with the COP9 signalosome (CSN) complex. Deneddylated by Epstein-Barr virus BPLF1 leading to a S-phase-like environment that is required for efficient replication of the viral genome. SIMILARITY: Belongs to the cullin family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
