Summary: TfoX 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.
TfoX C-terminal domain Provide feedback
TfoX may play a key role in the development of genetic competence by regulating the expression of late competence-specific genes . This family corresponds to the C-terminal presumed domain of TfoX. The domain is found associated with PF00383 in Q9JZR1. It is also found as an isolated domain in some proteins suggesting this is an autonomous domain.

InterPro entry IPR007077
This domain is found in a number of bacterial proteins including the TfoX gene product of Haemophilus influenzae. TfoX may play a key role in the development of genetic competence by regulating the expression of late competence-specific genes [PUBMED:7724607]. This family corresponds to the C-terminal presumed domain of TfoX. The domain is found in association with the N-terminal domain in some, but not all members of this group, suggesting this is an autonomous and functionally unrelated domain. For example it is found associated with SWISSPROT in INTERPRO.

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:

- show/hide the summary boxes
- highlight species that are represented in the seed alignment
- expand/collapse the tree or expand it to a given depth

There is 1 interaction 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 TfoX_C domain has been found. There are 4 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.
