Involved in ubiquitination and subsequent proteasomal degradation of target proteins. Together with CUL1, RBX1 and a F-box protein, it forms a SCF E3 ubiquitin ligase complex. The functional specificity of this complex depends of the type of F-box protein. In the SCF complex, it serves as an adapter that links the F-box protein to CUL1. SCF(UFO) is required for vegetative and floral organ development as well as for male gametogenesis. SCF(TIR1) is involved in auxin signaling pathway. SCF(COI1) regulates responses to jasmonates. SCF(EID1) and SCF(AFR) are implicated in phytochrome A light signaling. SCF(ADO1), SCF(ADO2), SCF(ADO3) are related to the circadian clock. SCF(ORE9) seems to be involved in senescence. SCF(EBF1/EBF2) may regulate ethylene signaling. Plays a role during embryogenesis and early postembryonic development, especially during cell elongation and division. Contributes to the correct chromosome segregation during tetrad formation. Arabidopsis thaliana (taxid: 3702)

>PF03931 Skp1_POZ: Skp1 family, tetramerisation domain; InterPro: IPR016073 SKP1 (together with SKP2) was identified as an essential component of the cyclin A-CDK2 S phase kinase complex []
It was found to bind several F-box containing proteins (e.g., Cdc4, Skp2, cyclin F) and to be involved in the ubiquitin protein degradation pathway. A yeast homologue of SKP1 (P52286) was identified in the centromere bound kinetochore complex [] and is also involved in the ubiquitin pathway []. In Dictyostelium discoideum (Slime mold) FP21 was shown to be glycosylated in the cytosol and has homology to SKP1 []. This entry represents a POZ domain with a core structure consisting of beta(2)/alpha(2)/beta(2)/alpha(2) in two layers, alpha/beta. This domain is found at the N-terminal of SKP1 proteins [] as well as in subunit D of the centromere DNA-binding protein complex Cbf3 []. ; GO: 0006511 ubiquitin-dependent protein catabolic process; PDB: 1LM8_C 2XAI_E 1VCB_E 3ZRC_K 3ZRF_E 3DCG_B 2C9W_C 1LQB_B 2IZV_C 1HV2_A ....
Domain in Broad-Complex, Tramtrack and Bric a brac. Also known as POZ (poxvirus and zinc finger) domain. Known to be a protein-protein interaction motif found at the N-termini of several C2H2-type transcription factors as well as Shaw-type potassium channels. Known structure reveals a tightly intertwined dimer formed via interactions between N-terminal strand and helix structures. However in a subset of BTB/POZ domains, these two secondary structures appear to be missing. Be aware SMART predicts BTB/POZ domains without the beta1- and alpha1-secondary structures.
