Summary: 56kDa selenium binding protein (SBP56)
56kDa selenium binding protein (SBP56) Provide feedback
This family consists of several eukaryotic selenium binding proteins as well as three sequences from archaea. The exact function of this protein is unknown although it is thought that SBP56 participates in late stages of intra-Golgi protein transport . The Lotus japonicus homologue of SBP56, LjSBP is thought to have more than one physiological role and can be implicated in controlling the oxidation/reduction status of target proteins, in vesicular Golgi transport .

This large clan contains proteins that contain beta propellers. These are composed of between 6 and 8 repeats. The individual repeats are composed of a four stranded sheet. The clan includes families such as WD40 Pfam:PF00400 where the individual repeats are modeled. The clan also includes families where the entire propeller is modeled such as Pfam:PF02239 usually because the individual repeats are not discernible. These proteins carry out a very wide diversity of functions including catalysis.
The clan contains the following 60 members:Apc4_WD40 Arylesterase Arylsulfotran_2 Arylsulfotrans Beta_propel CNH Coatomer_WDAD CPSF_A Cytochrom_D1 DPPIV_N DUF1513 DUF1668 DUF1900 DUF2415 DUF3312 DUF4652 DUF839 eIF2A FG-GAP FG-GAP_2 Glu_cyclase_2 Gmad1 GSDH IKI3 Kelch_1 Kelch_2 Kelch_3 Kelch_4 Kelch_5 Kelch_6 Lactonase Ldl_recept_b Lgl_C LVIVD Me-amine-dh_H MRJP Nbas_N Neisseria_PilC NHL Nucleoporin_N Nup160 PD40 Pectate_lyase22 Peptidase_S9_N Phytase-like PQQ PQQ_2 PQQ_3 RAG2 RCC1 RCC1_2 Reg_prop SBBP SBP56 SdiA-regulated SGL Str_synth TcdB_toxin_midN VCBS WD40
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the SBP56 domain has been found. There are 1 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
