This entry represent the BACK domain present in BPM proteins from plants, SPOP from animals and related sequences. BPM proteins are part of the Cullin E3 ubiquitin ligase complexes playing a role as substrate-specific adaptors of CUL3-based E3 ligases in the ubiquitin-proteasome pathway [1,2]. They bind at least three families of transcription factors: ERF/AP2 class I, homeobox-leucine zipper and R2R3 MYB, playing an important role in plant flowering, seed development and abiotic stress response [1]. SPOP, also known as HIB homologue 1 or Roadkill homologue 1 in humans, is an adaptor protein that forms a complex with Cul3, cullin-RING-based BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex, and is involved in ubiquitination of BMI1, H2AFY, and the death-associated protein 6 (DAXX) [4-6]. This domain is involved in dimerization together with the BTB domain (Pfam:PF00651), resulting in linear higher-order oligomers [7].	Domain

The BTB (for BR-C, ttk and bab) [1] or POZ (for Pox virus and Zinc finger) [2] domain is present near the N-terminus of a fraction of zinc finger (Pfam:PF00096) proteins and in proteins that contain the Pfam:PF01344 motif such as Kelch and a family of pox virus proteins. The BTB/POZ domain mediates homomeric dimerisation and in some instances heteromeric dimerisation [2]. 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 [3]. 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 [4,5,6]. The POZ or BTB domain is also known as BR-C/Ttk or ZiN.	Domain
