This family of proteins, which contains SH3BGRL3, is functionally uncharacterised. SH3BGRL3 is a highly conserved small protein, which is widely expressed and shows a significant similarity to glutaredoxin 1 (GRX1) of Escherichia coli which is predicted to belong to the thioredoxin superfamily. However, SH3BGRL3 lacks both conserved cysteine residues, which characterise the enzymatic active site of GRX. This structural feature raises the possibility that SH3BGRL3 and its homologues could function as endogenous modulators of GRX activity [PUBMED:11444877].

This clan contains families related to the thioredoxin family. Thioredoxins are small enzymes that are involved in redox reactions via the reversible oxidation of an active centre disulfide bond. The thioredoxin fold consists of a 3 layer alpha/beta/alpha sandwich and a central beta sheet.

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 UniProtKB sequence database using the family HMM
- 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:

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 SH3BGR domain has been found. There are 7 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.
