Summary: Type 5 capsule protein repressor C-terminal domain
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
Type 5 capsule protein repressor C-terminal domain Provide feedback
This domain is found in bacteria and archaea. This domain is about 90 amino acids in length. This domain is found associated with PF00149. SbcD works in complex with SbdC (SbcDC) which is a transcription regulator. It down-regulates transcription of arl and mgr to inhibit type 5 capsule protein production. It acts as part of the SOS pathway of bacteria.

SbcD works in complex with SbcC. SbcCD is a nuclease that cleaves DNA hairpin structures stopping the progress of the replication fork and allowing homologous recombination [PUBMED:9133662, PUBMED:18342610]. It plays an important role in DNA repair and in the maintenance of genome stability [PUBMED:17644583, PUBMED:9653124]. In Staphylococcus aureus, it is involved in the repression of type 5 capsule production as part of the SOS response by down-regulating cap5 genes via arl-mgr pathway [PUBMED:17704228].

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

There are 3 interactions for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
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 SbcD_C domain has been found. There are 12 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.
