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 ....

>PF00651 BTB: BTB/POZ domain; InterPro: IPR013069 The BTB (for BR-C, ttk and bab) [] or POZ (for Pox virus and Zinc finger) [] domain is present near the N terminus of a fraction of zinc finger (IPR007087 from INTERPRO) proteins and in proteins that contain the IPR006652 from INTERPRO motif such as Kelch and a family of pox virus proteins
The BTB/POZ domain mediates homomeric dimerisation and in some instances heteromeric dimerisation []. The structure of the dimerised PLZF BTB/POZ domain has been solved and consists of a tightly intertwined homodimer. The central scaffolding of the protein is made up of a cluster of alpha-helices flanked by short beta-sheets at both the top and bottom of the molecule []. POZ domains from several zinc finger proteins have been shown to mediate transcriptional repression and to interact with components of histone deacetylase co-repressor complexes including N-CoR and SMRT [, , ]. The POZ or BTB domain is also known as BR-C/Ttk or ZiN.; GO: 0005515 protein binding; PDB: 3M5B_A 1R28_B 3LBZ_A 3E4U_F 3BIM_B 1R2B_A 1R29_A 2VPK_A 2YY9_B 3GA1_A ....
>smart00225 BTB Broad-Complex, Tramtrack and Bric a brac
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.
